Occasionally it's useful to check which mods have loaded into the game before other mods. I don't know how much you want Modlist UI to become a developer tool rather than a simple user-facing one, but if you have room for another column this could be useful.

Mods are loaded in the order that you find them in script.active_mods, so you can check them by running

/c for i in pairs(script.active_mods) do game.print(i) end

but that does get a bit unwieldy for longer lists.

Another semi-related suggestion is the ability to see mod dependencies, but since you can already from the game's Mods menu, it's not a priority.

I can do the mod-order one by making it the display order when no sort mode has been chosen. Currently, when no other sort other than by Title is chosen, then [Title - Ascending] is chosen as the fallback.

I can offer the non-sort mode of Title, ie. nothing is picked and nothing is ordered, to then load the default order.

Wube's official mods will still remain in their section, and User-pinned mods will still be at the very top.

Load order is usually the alphabetical slug / [name] order, which is what we see when exporting the dependency array/info.JSON skeleton. Or should at any rate.

Scraping and displaying mod dependancies wouldn't be difficult, but the visual real-estate is starting to get quite crowded in expanded-accordion, which was meant to house the elements currently seen, and even then the whole Description field often doesn't fit.

Modlist UI is aimed to be streamer-first, and the list of developer-facing features is starting to get to a substantial point that I'm questioning what audience this is really for.

But back on topic, I can perhaps offer a hover-element, since those can be any size, but nothing concrete. Next you'll likely want that to be a fixed element one can actually click on the dependancies for, and it skip to that mod in the list.
