It all sounds great until you actually try to use the feature and it breaks everything... I obey the KISS rule... With over 200 ESP's in my load order, and with some of my mods being over 1GB each, it takes a life-age for NMM to switch to another profile. I find it far easier and much less buggy to do it manually.... which still takes over 2hrs for a complete reinstall. Also, NMM does not handle errors well and it's likely that it will freeze or crash while switching which is a waste of time and trashes your install.
