We don't need to have the best package management system, we need to have only ONE. Major Linux distributions are great for that.

I'm really happy that dale started to push that (even if keith was doing the same with Sake) because since the first day we worked with MC and used MC to manage 3.9 we were aware that we need such mechanism.

Re: [Pharo-project] Diff tools

Gary sometimes I know (since for example I already checked all the conflicts but the system crashes for another reason) that I want to take all the incoming versions or the working copy ones. Right now I have to go over the list each time (even if I know what I'm doing). in the old merge there was such buttons.
