MultiMod question...

Quick question, I only intend to use 3 mods from Particle Systems list for starters, Custom Jaf's, Free Roam, and Location finder, Do I have to have Multimod installed to use all 3 of them at the same time? Also if so, is that all I need?

Thanks

I would get UniGUI and zzLocationFinder version. It has many nice features (like favorites). Multimod is needed by basically everything.
