More Masteries?

so i also asked on discord, and from this thread Feasibility of UI modding right now? i take it its theoretically possible. Specifically because of these lines.

Just as much as adding buttons to allow managing more Masteries.
I do have a char with 6 masteries maxed and can reset that, but not in game, yet.
Currently I have to use cheatengine to reset masteries and then undo class selection if I want to change the skills I want my all class toon to sport.
I have solved the issue of being OP by maxing the classes. both in CE and game, but little point to it if the UI is as limited as it is right now.

If it is possible I’d want to make extra buttons to allow for managing each class directly.

and

Some minor UI edits have been done to get 9 masteries to fit on the screen. (See tutorials sticky) A lot of the UI is also in the dbr files, which would allow it to be edited. (I’m working on stash UI, hope to release tonight but busy.) Lastly, we don’t know what we can’t do yet, we haven’t hit the wall.
