jotdraft's Issues

Add Redo and Undo Features

This is nice to be able to revert changes. We should allow users to undo or redo changes.

Specification

We should save changes when user's behavior changes.
For example,

  • insert text -> delete text
  • delete text -> paste text
  • insert text -> move cursor
  • insert text -> idle for a moment

These actions indicate that user completed 1 step of editing.

Idle Moment Detection

We assume no text content changes while 2 seconds (may be changed later).

App crashes when saving a document with custom color spans.

How to reproduce

  1. Specify base style to Title
  2. input some text
  3. insert linebreak
  4. change base style to the other
  5. input some text
  6. insert linebreak
  7. try to select the end of line(long press at the end of document)

Add Dynamic Color Support

Backgrounds

Dark theme or Light theme, it depends on users. For now, Black is Black, White is White... regardless of themes.

It would be great if dynamically changes color of Document.

Idea

Define a single color by two colors which correspond to dark and light themes. Default colors will be provided by "dynamic" color.

When adding a custom color, we should allow users to determine which type of color to configure, "static" or "dynamic".

Application crashes when saving a document with applied OverrideStyle (such as Bold)
