Thanks, that clarified quite a bit.
Im in my stock rom (ICS 4.0.4) and something occured to me.
1. With all the apps having to be reinstalled to each "slot"/rom, it's kind of pointless to have anything less than 3gb per slot...
I checked my storage capacity while in the stock rom for the internal storage, it says it's total is 16gb, but only 2.97gb is "available. The only slot I have created and installed into is CyanogenMod 10.1 +gapps into slot 1. I recreated the slot last night with 3gb shortly after my last post last night. I didn't want to have to keep rebooting between CGM and Stock to get to my apps. but with how it is now, I cant even install another slot, only Stock and 1 Slot. I MUST be missing something. I mean, if you do have to toggle/reboot between slots/roms to be able to access and use all the apps that you normally use... thats... Ive just gotta be missing something. I really really want these roms so I can use the customization, like allocating app shortcuts to lock screen swipes... epic. But if the Slot doesn't even have the room to install all the apps I want, then it kind of limits or outright defeats the purpose of the rom, i think... This is all just thinking out loud and sharing my understanding of things and hoping Im wrong. Sry.
