I mean I'm not opposed to having it switch automatically, It just looks really complicated to (a) store that for each toon and (b) figure out how it should look in the UI.

I think I can safely say this isn't going to happen

LibDualSpec requires that's you're using

local AceDBOptions3 = LibStub('AceDBOptions-3.0', true)
local AceConfigRegistry3 = LibStub('AceConfigRegistry-3.0', true)

neither of which are true for LiteMount. It's no use I'd have to DIY.
