I like Boxy, however...
Overall I like the app. I think Google’s design for Inbox is fantastic, and only keeps getting better, so thumbs up for not differing from that. My only complaint with Boxy though is it “feels” really unresponsive. I am running a 2015 MBP so there shouldn’t be a reason for it running slow. There may be some unresolved memory leaks it seems as well, as I have noticed at times the memory usage can get unusually high and requires a restart.
Hopefully these are just some kinks to be worked out from the 1.2 release, but until then I can’t see myself using this over leaving an inbox tab open in my browser.
