When you change your mod list and attempt to load a save that doesn't have all the mods enabled/downloaded, it would be nice to have a "Select All" checkbox for each category of "Not In Save", etc. to avoid unchecking 50+ checkboxes for some crazy people that have a ton of mods.

Why does the “sync mods” option when loading not work?

Suggestion is not very clear. It seems they mean the case when you want to load a modded save with fewer mods, i.e. only the mods that are already downloaded or already enabled, but do want to sync startup settings?
