https://github.com/rbreaves/kinto comes close for keyboard shortcuts
I suspect once I package it properly and make it available in various repos and app stores that it will get more coverage. Also Kinto is feature complete as far as I am concerned, only changes that happen now are mostly minor. May do a rewrite of some parts of it to make updates go smoother and allow users to retain their own changes easier but no major functionality changes or additions are planned at this time.
Works flawlessly on Windows and Ubuntu for me :-)
Makes life worth living! ;-)
