possibility to assign several keys for one contact
Problem
I'm(and my friends) using this model: for not running into problem of compromising the single OpenPGP key we have each one for every place we have a computer: e.g. one at work, one at home, one on laptop, one on smartphone.
Analysis
Currently Gajim does not have this feature. So every time you have to reassign user a key. He gets home, you have to reassign. He gets to work, you have to reassign. He uses laptop, again you have to reassign.
Enhancement recommendation
So it would be great if user could assign several keys for one contact.
