So it might be just me, but I love it when im able to collapse things when they dont need to visible.
I know you can nest text, color and other styles on the right side, but it would be nice to collapse those parent categories as well. Im working on a screen that is not the biggest and it would just be nice to see the active plugins at the bottom. I dont need to see all my styles that im using all the time. Plus having it collapse gives it a cleaner and neater look when you want to clean up your document (imo).
Let me know what you guys think, like I said it just something personal that bothers me, but its not that big of an issue.
Have a nice and productive day!
