I try very hard not to use command lines in Mageia and MCC has proven the best interface I've come across. I am sure that anyone (not using beta (cauldron) releases) will find MCC more than sufficient.
Anyway, there will be commands like "urpmi --clean" and others that will help what you wanted.
And as a long time user of Ubuntu, I find other "extraneous" programs like grub-customizer, ubuntu tweaks, super grub, burg-grub, etc not only unecessary, but can (and do) cause problems later on as upgrades cause dependency/conflicts, etc. Just use "apt-get autoremove, apt-get autoclean, ..." for your needs.
This is where Mageia stands out (and the easy installation of proprietary drivers and ....)
Cheers.
So, what does it do that MCC and the settings in KDE / Gnome do not?
I would also be interested in that.
me too, in addition.........."what does ubuntu tweak that the ubuntu OS cannot?"
