Seamless weapon switching and a couple other thoughts

I like to play as a blade and bow type character but i have found i have to stop any actions before i can switch weapons which is a little irritating is there any way to make this a little more seamless? I also had a thought about a new gem called "hasty exit" when your swarmed i thought it would be handy to be able to be teleported out of the ruck giving you the ability to run like **** or potion up and continue the fight with a mana burn cost rather than a straight up mana cost. Dont know if this is already done but it would be real handy.

I believe it's a hotkey?

Ye I have it set as the space bar, what I am saying though is I have to stop everything rather than just tap it to switch

your 'hasty exit' gem is called smoke mine.
