Cool stuff! The cycle aspect of anim scrubber is awesome.
As far as getting it to work in other windows, you can just place the hotkey in the ‘Screen’ section of the input (hotkey) editor. Then it will work everywhere. I don’t think it interferes with anything there, but double check your own setup…
BTW, I thought the channel mute didn’t work either since I quickly tested on an object - but it works fine here on armatures. It would be cool to be able to isolate specific channels when multiple objects(bones) are selected.
@draguu Thank you very very much, I really need it. The Blender Community is so kind and you are so amazing !!! @FrankieH Your original Addon, I’m using it for every animation work. Thanks for your creation !
