- Closes#976
- Added helper to apply arbitrary colour to an icon.
- Fix#979 - low res icons in night mode.
- The icons and colours are not perfect - please feel free to send
through a PR if you can improve them.
- Convert colors dictionary into module consts, so we can
use code completion.
- Added "Edited Today" and "Due Tomorrow"
- Rename camelCase attribute to snake_case and tweak the wording
of some enum constants. We've already broken compatibility with the
major sidebar add-ons, so we may as well make these changes while we
can.
- Removed Filter button. Currently there is no exposed way to toggle
the Sidebar off - wonder if we still need it?
