Since Bagnon 10.2.10, it implements its own Reagent Bank Menu Button.
Thus, this plugin here is no longer required. :-)

Bagnon ReagentBankButton is a simple Bagnon plugin adding an extra menu button to toggle the reagent bank.

I like being able to toggle the reagent bank on and off, which is normally only possible with the reagent bank button in Bagnon's "Bag Slots List". As I do not need this rather obstructive "Bag Slots List" for any other purpose, I implemented Bagnon ReagentBankButton to append a duplicate of the reagent bank button to the Bagnon menu.
