Love Tuple, use it daily. It really is the best for pairing.
The one thing that is annoying for me and can probably find out myself, but I think it maps cmd-a to something so I can't use it to select all.
If, however, you only see that problem when Tuple is running or call is active, let me know and we'll look into it.
