When you are making a new pack, you have like the main mods and the other tiny mods that do one thing, and they all combine and be really unorganized. I suggest a package system to curseclient modpack creation. Like how eclipse have packages, so you can sort your mods like "utility", main and clientside. Or even you can make a package that ia called "optional" so not everybody has to download it while installing.
Curseclient is such a wonder, and needs to have more abilities to be really powerful.
