[limo]

Hello all,

here is small patch for 1.1beta6 which will add buttons v (view trigger), e (edit trigger), i (edit item) to overview screen. It is usefull for me. Feel free to use

Please note this is only proof of concept, not real sollution. But if you like this think, maybe it will be usefull in next versions.
