It's nice that the launcher now tells you before you get in a Q if your files are not updated..
But can we get it to actually update before/when clicking the "Setup DLC and Mods" button
or at least indicate that there is a newer version of the mod and the dropdowns for each mod lets you choose to update within the setup browser.
It already has the options to find(search workshop) missing mods, should let you repair/update too.
