I've noticed that if you use dark mode when you highlight text with your cursor, it doesn't change to an alternative color showing how much you have highlighted so far. This only appears to apply to an open text box, not existing and previously submitted text. Something really minor but maybe something really simple to fix. Sometimes I like to edit out chunks of what I'm typing and if I use the cursor to do it, I don't get a visual representation of what I'm actually highlighting.
