Just took a look at the Editor/GM mode stream (took me long enough). Absolutely LOVE the idea of modder-created templates for GM functionality. Think that's a really wise way to go that adds tons of flexibility, but also allows a GM's life to be easy (or hard).
The only consideration in this is how an END-USER will grab these mods. This might be something we, as a community, have to develop. We need a robust website/game UI that automagically downloads all necessary mods. BUT, this also shouldn't bloat a player's game, which means some templates should be shared and not re-downloaded. It will be very difficult for anyone to create a functional pre-programmed system for this. Instead, we should focus on putting together 'community packs' of useful functionality that can be easily shared as a single download. Enhancing UX. Maybe Larian could curate the most popular mods and put them into endorsed/approved packs. A great mod community will only form if we have great user experience. Part of the responsibility rests on Larian to develop great systems. But part of that responsibility also falls on us, as a community, to develop great culture.
