Well, having dug a little bit into it, load-on-demand for the Looter loot lists is certainly doable, but not in the way I would prefer so far as I've found, I'm still trying to see if there is another way (for instance, I don't want to have to do it the AtlasLoot/Lightheaded/MobMap way with basically one folder and consequently box you have to check, for each of the Looter lists). If nothing else, I might leave the main toggles alone and just make the 'bigger lists' on-demand, but seeing as how that's not done yet the next version of Looter will be 1.0.11 and not 1.1. As of the moment it will simply be the "Extra Profession" loot as has been talked about in the feature requests area, such as Spider Silks, Venom Sacs, and various items that are used by the professions but don't fit the main loot options (also includes motes, essences and elemental "type"'s).

UE 0.04b adds the useguild toggle, or in other words, when toggled on (off by default) allow guildmates to use the whisper commands or be considered for the auto-accept options (party invite, summon or ress). Also added the reload/reloadui and show tracking slash commands to the help list (they were already implemented, forgot to put them on the list) which is both simply a reloading of the ui, and showing the tracking minimap button respectively (read the readme, or changelog on WoWI/WoWUI for details on the show tracking).
