I was checking around, b/c I actually find using the command line much quicker and more effective than any compression programs GUI. So I looked to see if not only was their a good GUI, but one that supported the most formats. I found slim to nothing, and the ones integrated with like FileRoller w/ Konqueror, left much to be desired. So before I start, I just wanted to find out if anyone here has knowledge of a good GUI that provides a frontend for creating/extracting from multiple compressions.
