Recognize tabs within an app
I've set AltTabby to recognize tabs within an app (under the filter settings: “Recognize app tabs”). This works with Firefox, but not with my other programs, such as Betterbird, Textmaker, or PDF-XChange.
Is there a way to tell AltTabby that these programs can have their own tabs?
Or would it be possible to “override” the Alt+^ hotkey for these programs so that I can use this hotkey to switch between tabs within them?
