I am new to Linux, and there are a ton of different desktop environments. It's hard to figure out what's what. So for you guys that have tried several different environments, which one(s) in Mint allows the greatest customization in relation to themes/colors, and is the easiest to modify such things in? Changing window title bar colors, window colors, task bar and main menu, icon colors/themes.... I'm currently using Cinnamon, and it's very hard to change these things, or at least it's not intuitive enough (I think I found where, but the options never seem to change when I switch themes), or I'm just too much of a newbie... As near as I can tell, the pre-loaded themes change only the task bar and main menu, but nothing else. I found this site called Gnome Eye Candy
http://gnome-look.org/index.php?xsortmode=high&page=0&xcontentmode=167, and I'm wondering if Gnome themes work in Cinnamon? I also found some more themes on Deviantart, so it'd be cool to know what is compatible with Cinnamon and what isn't, to help me choose a Mint flavor.
I need to change over to 64-bit Mint, so this gives me an excuse to try a different DE, thus my questions.
[Edit] I was browsing the Gnome Eye Candy link I put above, and noticed a section in it called called "Metacity".... isn't that what our window theme is called? Would these thems work in my Cinnamon? I'm so clueless, sorry.
