These are non-technical just going over concepts.

Another good idea to keep in mind(I didn’t see this in your screenshot) if you have a button on an edge or corner have it go all the way to the corner or edge. Yeah it might look good with a border and you want the border a seperate asset but people who don’t have the best hands (many people on computers all day) can then slam mouse to edge and be good. Giving a 20 pixel border which is non-clickable just makes this harder.
