Detonator for hunters

There is one important thing, playing hunter if you use traps... There not exploding exactly when you want! ... sometimes comes a moment when enemies go trough traps, and there not exploding.  ... I think, when hunter puts a trapa, the window with detonator should appear - just like window for manipulating pets. .... Every single detonator for every single trap 
Exploding trap - alt+1
guided trap - alt + 2
paralysis trap - alt + 3
Bomb trap - Alt + 4
