version3-2's Issues

Proposed extra shortcut keys

When this feature is adopted, 3 conditions should be considered.
1: nothing is selected (tool switching hotkeys)
2: when a bond is selected (bond hotkeys)
3: when an atom is selected (atom hotkeys)

Key action
Esc Switching between the Lasso/Rectangle Selection tools
0 Draw any bond

1 Single / Single Up / Single Down / Single Up/Down bond. Consecutive pressing
switches between these types.

2 Double / Double Cis/Trans bond

3 Draw a triple bond
4 Draw an aromatic bond.

Avoid clipping of multiple bond

Is your feature request related to a problem? Please describe.
Currently, the bond would just overlap each other which would mean there is an ambiguity to interpret as another compound.
Compound in this example is cyclooctatetraene in its native "tub-shaped" conformation

Describe the solution you'd like
A little gap would appear to avoid overlap

Drawing of Markush Bond

Describe the solution you'd like
A functional group can be attached to middle position of a ring
Describe alternatives you've considered
This (spaces generated between the ring and the appendage)

"Cannot edit Range" Error

Describe the bug
"Cannot edit Range" Error

To Reproduce
Steps to reproduce the behaviour:

Draw something on 2 different word document
While it is calculating
Click a Chem4Word equation in another document
See error

Unable to delete structures from Library.db

Opening the library displays structures but there is no 'X' to delete the structure, in the bottom left hand corner.

Thanks
Tony

Not able to open the editor when only the reaction arrow is presence

Expected behavior
Should open up the editor

Screenshots

It doesn´t work on my system

After installing the full one, the Chem4word tab does not appear.

An attempt is made to force the tab to appear by clicking on "COM Add-ons" and activating the tab corresponding to the add-on.

The add-on is not activated and if you go back to the same "COM Add-ons" window it looks like it is still not activated.

Template Library

Is your feature request related to a problem? Please describe.
A template library implemented in the editor
Library includes both standard and custom user templates

Describe the solution you'd like
After double click the template, the structure is save to clipboard. The user then can click the space in the editor to paste it.

Additional arrow types

Describe the solution you'd like

Retrosynthetic arrow: Shows precursors for a given molecule

Dashed reaction arrow: shows a theoretical step(s)

Connecting arrow, allow a new arrow to be drawn from existing arrow

With a beginning- , mid-, ending- point anchor shows when pointer hovering on it

when another arrow is near the anchor point, it will attach to it
example: straight arrow attach to curve arrow at mid-point

Example

Different kind of curve arrow, fishhook arrow

Size of reaction arrow and molecule does not change when there is no bond

Allow bond orders other than single bond order have stereo option too

Is your feature request related to a problem? Please describe.
Currently, only full bond order has stereo option.
In case of μ-amido-μ-hydroxobis(tetramminecobalt)(4+), if we want to draw NH₃, then we need to choose half bond order and not having stereo option.

μ-amido-μ-hydroxobis(tetramminecobalt)(4+),

Add the pi electron structure for benzene.

Hi,
I'm a student in the UK. For the vast majority of cases, the skeletal formula of benzene that showcases the pi bonding structure (the hexagon with the circle in the middle) is the only relevant skeletal model. The alternating double bonds represent the Kekulé model which is considered "wrong" in most syllabi at my level of education.

I would appreciate it if the pi bonding model could be added.

Thanks.

Not able to access molecules properties with [CH₄]

First draw this structure

then delete one of the CH₃

I notice there is no count n option in molecules properties

Problem of calculating the valence electrons

Describe the bug

The editor keeps adding hydrogen when the −ve charge is increasing in order to keep the valence electron the same.

Current behavior

Expected behavior

with the red circle indicating there is an error in valence count

The alignment of the render does not match the drawing in the editor

Edit: Added markdown to format cml nicely.

Allow the creation of multiple libraries in addition to 'Library.db'

Chem4Word /library/open has only one choice for the library to open - library.db.

In order to separate various structures from one type to another, it would be advantageous to have the ability to choose one or other library to open rather than the 'pre-set' 'library.db'.
For instance, the ability to create new database files and give them their own names:
organic_acids.db
organic_bases.db
etc.
The databases could all be kept in the same folder as the 'library. db' database, so there's no real need to go to special lengths to make other folders 'selectable' - just a simple 'drop-down', as per the existing program, but with additional choices of databases.

Charge on bracket mismatch (in the editor only)

Describe the bug
There is a -ve charge on the upper right when it shouldn't
The compound is Vinylcyclopentane
To Reproduce
Steps to reproduce the behaviour:
It shows a -ve charge on the upper right.

Expected behavior
no charge on the upper right

Edit: Add markdown to display cml correctly

Placement of ionic charge

Describe the bug
Currently the charge is place on the upper right of the atom rather than upper right of the polymeric ion

Describe the solution you'd like

Screenshots
From IUPAC Red book

Describe alternatives you've considered
Place charge on the upper right by default and allow other position.

Bond type: dative, connector

Rendering of MDL functional groups (from MOLFile)

Allow change of length in bond properties

Describe the solution you'd like

Describe alternatives you've considered

I understand that we can drag the bond, we can't do it very precisely.

Edited to put this irrelevant information to the bottom.

In current version, Chem4Word 2020 Beta 8, the default bond length for 1 letter elements (e.g. C,O,N) and 2 letter elements are different (e.g. Ru)

Error occurs after editing a structure next to an equation

Describe the bug
I get the following error after editing a structure wich is next to an equation.

Screenshots

Chem4Word ribbon greyed out (except Options and Help) when opeing word document in compatability mode.

Having added some downloaded structures to a word document, via chem4word, when I reopened the document a few days later, when I open the Chem4word ribbon all the features are 'greyed out' except for the "Options and "Help" buttons.

If I open a new, blank, Word Document then the Chem4Word ribbon is active.

To Reproduce
Open saved document with Chem4Word structures embedded and the chemistry tab ribbon is inactive.

Expected behavior
Chemistry ribbon should be active

Screenshots

Most of the reation toolbar buttons are greyed out

Are they not ready in this version?
