deprecation notice to plugin compatibility shims
- When qml-common became a thing, we left qs.Widgets shims in place for
plugin compatibility
- It's annoying to need to maintain them when qml-common has any change,
add a warning so we can safely deprecate them in the future
- One shot rename the common stuff to D to make it shorter and nicer to
write
- Add a full popout Notepad experience w/new layout settings
- New ability to choose the left or right side of the screen
- Add more safegaurds to preserve user data throughout
- New banner to show file reload/conflict handling
- New extensionless file support
- Polish settings with gap controls, compact buttons, and shortcuts help
