Only checking for missing/deleted files

I find the tool is seriously cool and useful and offers a better service than options like CurseForge's own launcher, but I think it's a bit cumbersome to have to use the update function if I only want to find mods that no longer exist on CF or which had my active file removed. If you could add a command that simply only outputs a list of mods that have these issues, that would be perfect, because publishing a larger pack to CF is always a pain due to them only ever telling you the first mod reference that trips up, and not even answering to direct questions.

I couldn't really understand what your issue is, but I thought that #49 would be relevant to you; dry-runs would allow you to run ferium upgrade without actually downloading the files
