As to what else might join your housekeeping list ....
I haven't yet used R9 microwatt beyond a superficial look at launch, but I have noted multiple posts from interested users. It looks as if the new UI has been popular and successful, and while it might not immediately suit someone migrating from the Win-world, it could be a realistic alternative or more than the high-tech few. And a point of difference for wattOS. So I reckon that some collation of available material for new-to-i3 users is warranted, in the wiki. Promote any included wattOS support (eg easy install of chosen mainstream software), and any apparent limitations which come with i3/Microwatt, to save angst later on.
Concerns are appearing (other forums, fellow Linux users, ...) about the future of LXDE, as opposed fo LXQt. Many of these are unnecessary worrying. It's plain that LXDE is still being developed and improved, but only if one actually goes and checks this. It also seems there is still plenty work to be done to get LXQt to the same quality as LXDE. It would be good to have your view regarding wattOS and LXDE, when there is enough substantive info available to you to make such a statement.
