Is your feature request related to a problem? Please describe.
I like the separation of "normal bank" from "reagent bank".
But I don't like the bag list on top of my bank frame.
Unfortunately, the "reagent bank" button in the bag list seems to be the only way to toggle between "normal bank" and "reagent bank".

Describe the solution you'd like
It would be nice to have an optional "Toggle Reagent Bank" button in the menu right next to the "Sort Button", "Search Toggle", etc.

Additional context
A mockup I photoshoped (The number of empty slots would not be necessary!)

I moved this feature to a stand alone Bagnon plugin:
