I was thinking on it and I came up with an idea that I thought would be nice. In my previous posts, I have been talking about my issue with user interface clutter. One of the things that I thought of that could be nice is the ability to make custom macro icons to use in the macro bar. That way, you can use images that help you remember what does what without having to read text. Something that comes to mind as an example of what it could look like is the World of Warcraft macro dialog menu. They give you that huge list of images for your macros. I'm not implying that Roll20 is like an MMORPG. I am only trying to give an example. With that, I think that it would also be possible that you give the player the option of uploading their own image to serve as the icon. That way artsy players, like me, can make their own icons.
