Is your feature request related to a problem? Please describe.
I am very picky when choosing addons because of how they affect the visuals of the game. For your addon, my peeve is with how the buttons look and that there are functions I don't use cluttering my UI.
Another thing is, I'm missing the ability to track more than 3 currencies.

Describe the solution you'd like
It would be great to have an option to disable each button individually. For example, I don't use any "between characters" or "on the go" functions, so I don't want to have these buttons on my UI, even though I use the sorting button a lot and would like to keep it (although it would be nice to have it adjusted so it doesn't overlap/clash so much with the rest of the clean base UI).
For the second issue, please allow for more than 3 currencies to be tracked. Thanks!

The additional currency tracking has been implemented now.

There's no plans to control button visibility individually.
