A note of warning to anyone planning to use the merge feature. Many of the mods will not be properly categorized and this will likely cause some load order headache. I haven't experienced any major issues so far, but I am stuck with either redownloading a good handful of mods or getting the blackface bug on every other npc. Personally, if you're set on switching, use NMM as a download link list, it will save you the hassle.
