Firstly: Push 2 is superb. Love it. Thank you Ableton people. Next time I'm in Berlin I'm bringing you beer. (You gave me beer at your party/Kompakt shop a few years back so I need to return the favour anyway.)
Secondly: TAP TEMPO, PUSH 2. My feature suggestion is this. Possible firmware update: Hold down Tap Tempo, enter your tempo via the Pads. Simple, but I think it would improve the usability without changing much existing functionality. You can still enter Tap Tempo via the button, but holding it changes the function and accesses the pads for tapping. It's very unlikely to be accessed by accident, because no-one ever holds down Tap Tempo, right?
Tapping in tempo with those clicky rubbery buttons is difficult. It's the only thing in Push 2 which I feel is not well implemented/designed (everything else is 100%).
But take your time. You've earned a rest.
