Request: Spell check, Keyboard Control, Undo/Redo during Prompting

It's a great tool, but please please please impliment at minimum browser standard input support, meaning:

1. Spell check. Very important.

2. Keyboard control. When I am in generate prompt field and I press ctrl+left or right arrow I am attempting to select a word, not move my mask and clear my prompt.

3. Proper undo/redo would be nice

4. Somewhat unrelated and potentially not inline with the "workflow" style here, but if I am trying something and I accidentally click away the propmpt is gone, can't get it back.
