I guess I could download this, as I really really do have the messiest .minecraft directory. What separates this from Curse's client, or Magic Launcher?
I haven't used Curse's client or Magic Launcher recently. I don't believe they install or delete saves or texture packs, and though Magic Launcher can use a different jar than the one installed, I don't believe it can install a new one.
MCManager has some features that the launchers don't, but if you don't use those features, the Magic Launcher would probably be more convenient.
I've had trouble with this first couple mods they worked but then I added two more but they didn't work so I tried to remove the two mods that didn't work and the mcmanager stops working andi cant fix it wat do I do?
Okay but what is the actual use of this? It doesnt look like it can do anything thats normally super hard to do. Find .minecraft? Can just open game directory VIA launcher. Install mods? Just drag and drop in the folder. Resource pack? Drag and drop. Clear Minecraft folder? Well you can just delete .minecraft, run launcher and you got a brand new, freshly generated one. I see no real use to this ohter than just being ultra lazy, in which case how could you install something like this if you cant even drag and drop a file?
