I would be good to have a traditional changelog for each SU with a rolling update on known issues as and when they become significant, in particular market place mods. Yes to a point it already happens but it is rarely updated. Unlike now a search for e.g. “1.21.18.0 known issues” should always land at the requested page.
My other suggestion is that 3rd party marketplace mods should have their own Official II folder for ease of testing. Of course I realise this might exclude X-box users as is so in content manager I also suggest adding a disable function and not just delete. This gives an added benefit that mods with known conflicts could be greyed out on load but would still be choosable by those willing to risk their use.
