Quote from Discord:

[...] Why not make both zooms have identical options, just different keys? Y'know, like JourneyMap has two map presets with identical options

To achieve it option-wise:

Make "behaviour", "scrolling" and "controls" categories instead of tabs
then make two tabs [- primary and secondary zoom] with these categories [inside]

so overall there will be 4 tabs:

• primary zoom
• secondary zoom
• spyglass
• misc

If I were to do this, I don't see a reason to stop at 2. I can probably get an extra add button in the categories to add an unlimited amount, but it may need a lot of changes in YACL.
