(Feature request) Way to easily backup only FOMOD installers with this plugin

[genderneutralnoun]

Hope I'm not stepping on any toes here, since this is the first issue for this plugin... What it says in the title, essentially. I was thinking either a way to filter to only show FOMOD downloads in the drop-down list in the Reinstaller window, or maybe even something like, add the ability to add the download file to the Reinstaller backups via the right-click menu in the downloads window. Auto-backups would also be amazing, but probably hard to implement, I'm guessing. I install a lot of mods at once and manage several different profiles in one instance, so the Reinstaller functions are a must for me, but keeping track of which mods are FOMODs or not can be a real headache.
While I'm at it: I'd absolutely love a way to automatically make different files for a mod into separate MO2 mods when installing. As I mentioned, I use many different profiles in one instance, and sometimes when mods package patches separately instead of in a FOMOD, it can be hard to keep those patches separate from the actual mod so that profiles that don't need that patch don't have the patch enabled.
Anyway, these are all just suggestions. Regardless of whether you like them or not, I greatly appreciate this plugin and your work. Please keep it up. :)

I'm sure some of these things would be possible, although could pose issues potentially in implementing them in a way where they don't cause any lag!

• To only list FOMOD installers, or to have a filter for them, there'd need to be a way to identify FOMOD installers quickly. Currently, the only way to do this would be to unzip the download and look for the FOMOD config, which could be fairly slow for larger mods, certainly possible to identify though. I generally only ever use Reinstaller with FOMODs at all, so I'm not entirely sure of the use case, if you let me know your workflow though, maybe I might understand better and have an idea of what would be the best way to do this?

• I don't believe there's any way to alter the context menu for MO, so I wouldn't be able to add any kind of right-click backup functionality without prior alterations to the MO API. Would definitely be a nice feature though!

• Auto-backups would actually probably be easier to do, since there is an 'onDownloadComplete' which can be used to check the file that was just downloaded, although how to identify if it's one to automatically backup might pose a bit more of a challenge, I'm certainly open to any suggestions though!
  It might be possible to have a workflow where when a download completes, it uses the download id to find the file name, then looks for a metadata file with nexus information, compares that to existing metadata for Reinstaller mods, and then adds it to Reinstaller if it matches the Mod id, but not the Download id. I imagine this would need a per-mod setting though since it could be annoying to auto-backup a bunch of other files if you actually only wanted one of them.

I keep a lot of profiles separately too, generally if a mod comes with a lot of individual file patches, I just install all of them as separate mods and enable them per-profile, usually I'll just use the dropdown when installing to select the file name instead of the main mod name, but I think I get what you're talking about.
If the mod has a FOMOD patcher instead, I use Reinstaller and just do one patch bundle per-profile which I can reconfigure later!
