Well, it's a good thing for newbies, but is there something between synaptic (which shows every single package) and the "software manager" which shows only a few ? Something like Ubuntu's old "Add/remove" or the new "Software center" (which is, actually, pretty nice I must say) ? Is it possible to install one of those ?
For now I'm stuck with "sudo apt-get install XXX" to install hidden softwares like bkchem or xournal... It's not difficult, but maybe Linux Mint lacks a software manager for average users.
EDIT : Well... "sudo apt-get install software-center" actually installs Ubuntu's software manager... And it works. You know what ? I'm happy.
