Copy from does not work if selected from dropdown on inactive bank tab.
For example, if active tab is bank 3, but we go to bank 2 dropdown and select there "copy from 3" - it does not copy value.
Tab needs to be active in order for its "copy from" dropdown to work.
If I remember well, the bank tabs are fake tabs.
There is not a component per tab, just a single component whose content is changed as tabs are selected.
A quick fix might be to force a tab to be active when using the gear icon.
Same issue affects other action: swap, restore, reset.
Probably it does. But the main problem here was this - doing the autotune on #3, reviewing it, and then copying to #2 (still #3) active, hitting "save" and unplugging and going out to the field. Without realizing it wasn't copied, and #2 bank sucked big time.
I submitted a fix that should address all cases.
