In Nure classes are always start and end at a specific time (first class is always from 7:45 to 9:20, second is from 9:30 to 11:05 and so on), but current calendar in this application doesn't represent that. It starts when first class for given timetable starts and than have time markings after each hour (which don't match start and end time of the classes).

This is known issue and currently there are no plans to fix it. Here is why:
As of now NureTimetable uses SfSchedule control for displaying classes. Unfortunately it doesn't support variable time spans for rows. Each row must be the same length. And since (thanks to breaks between classes that have different length) classes start 95 ± 10 minutes after each other, it's not possible to choose such time interval that would match at least the start of each class. So I choose 1 hour to be as the time interval (I tried 1.5 hour, but it was worse).

There is possible workaround. I've opened feature request regarding this and proposed solution was to add Non-Accessible timeslots in place of breaks. And it is good solution, but currently minimum length of those is an hour. Soooo. Here is feature request to Enhance the NonAccessibleBlock feature with Minutes. You can vote for it, so it will get implemented faster.

Add "TimeBefore" setting

protobuf-net provides 2-3x performance improvements, and since this app relies heavily on serialization, benefits will be very noticeable

Every night cist is performing timetable update and during this time it returns error 503. I will be to indicate to users that timetable will be available soon

Dates are duplicated next week. nuretimetable

ListView supports multiple data templates per view and item grouping: https://docs.microsoft.com/en-us/learn/modules/customize-xamarin-forms-listview/4-exercise-create-and-select-custom-cells

Ability for users to create custom events

Ability to upload whole timetable to google calendar, and then add new events and delete removed ones

Display event number based on how many there are events with the same type before it

After transitioning to MVVM pattern, there is a performance hit because Xamarin needs to use reflection to communicate with ViewModel. By spesifying x:DataType parameter for Views with their respective ViewModels we allow Xamarin to link them at compile time thus improving rintime performance.

• Find next event with specific lesson and/or type (when the next lab work in physics)
• Search for event with specific note (after implementing #20)
• Count (how much labs do you have left)

Instead of this:

Use SfPullToRefresh or similar control on TimetablePage to be more user-friendly.

Add ability to create event in google calendar that matches selected event in the timetable

when you live abroad, it is hard to understand at what exactly time lessons start, like I leave in Georgia, and have +4 GMT and must add 2hours, and cant get notifications in correct time (maybe make optional setting o show ukraine time or own timezone)

Ability to add a note for any event

Add ability to reorder saved entities.

Here are examples of how to do it:

• https://help.syncfusion.com/xamarin/listview/item-drag-and-drop
• https://github.com/roubachof/Sharpnado.HorizontalListView

Bring back CSV parsing, like in a good old days!

Pros:

• Ability to update multiple timetables at once
• Much faster update speed

Cons:

• Less data will be available (no teacher full name and no group list)

Lesson info include:
• Teachers
• Class count (total and grouped by event type)
• Date and time of the next class of each type

Replace regular loader with skeleton one on "Saved entities" and "Add entity" pages

People don't update university entities list, and expect that new groups will show up there by themselves.

If after update something changes in timetable, user will be notified

Proposed N = 7

So, issue title says for the issue itself.

Screenshot with crashlog:

Let app itself notify user X minutes before the event, so user don't need to add event to google calendar for this purpose

Add feature that lets users to view time until break. It may look like this:

Background color of splash screen should depend of the theme (light or dark)

This could be a useful feature (especially in combination with #18), but I don't want to overload cist with several thousand simultaneous queries.

Proposed solution: Only one (selected) timetable will be updated at random time between 6 and 8 am

Don't block UI thread when timetable is updating
And update timetable when it's added (without notification about successful or failed update)
