While you're messing around with feral attack power it would be nice if the spell related summaries and breakdowns could hide when in cat/bear form and show when in caster/tree/chicken form.

Or, alternatively, add a toggle/hotkey to swap between showing different sets of. I have similar problems on both druid (showing both resto and feral stats) and on warrior (tank vs DPS stats) getting very cluttered, so multiple comparison profiles would be nice.

The solution I'd probably choose would be to implement LibDualSpec, rather than automatically switching based on forms or providing keybinds.

In the meantime, if you'd like to create your own keybinds, RatingBuster's profiles use AceDB, so you could choose to swap between profiles in a macro using something like this:

/run RatingBuster.db:SetProfile("Shaman")

tbh, only seeing your active spec is rather limiting in that it makes evaluating offspec gear very tricky. Sometimes I only want to see the healer/caster stats of an item even when I'm in a different spec.
