Not sure if it's already been suggested, but have you thought about maybe adding some sort of resource / snippet section? Like, maybe something similar to the scratch pad, but it comes with a couple snippets / reminders of common things, like tabs / columns / links / images / etc, or a list of fonts, a key to the colours (primary, warning, danger, etc) that could be helpful for beginners (and/or people with bad memories like myself lol)? I know the scratch pad could be used similarly to this, but I feel like it ends up getting quite crowded and hard to go through when there's coding snippets, notes on what I wanna do, character notes, etc all in there, plus this could come with a couple things built in and we can maybe add to it? This probably isn't a super important thing to add, but maybe if you're just looking for something it could be an idea! It could perhaps be something you bring up rather than crowding another box on the screen, like how when you click the info button in the corner it brings up that pop up, maybe something like that? (sorry this got really long, hope my point got across okay through all of this!)
and just a small edit I thought of on the topic of the scratch pad getting crowded, what if you could add tabs to it? That way you could make a tab to write your character notes, make another for snippets, another for saving a link to something, whatever else you would usually write in there! That could be helpful for people who like to write a lot of different things in there!
