* Declare toolbar api via modifiable property * Fix addon buttons * Assign editing areas in a synchronous way * Restore the Tab shortcut that moves the caret to end - moveCaretToEnd is called twice now: The moveCaretToEnd calls in *TextInput causes the caret to be moved to the end when switching back from the window and back. - To fix this, I will need the code for saving and restoring locations from #1377 * Restore selections in the PlainTextInput * Improve type safety of destroyable - clearable-array was renamed to destroyable
