Syncthing may not have its own Web-based file browser but a regular Web server (like Apache or ngninx) can show a list of files in a directory without much configuration. Just point it at a shared folder. You could configure a fancier file browser like Filestash, File Browser Quantum, or even Nextcloud if you feel it's worthwhile.
Likewise, Syncthing may not have its own concept of a "main" hoster, but it doesn't need to: you can decide what "main" means to you. Perhaps the one you designate "main" has different ignore patterns, or a longer retention policy.
"Keeping some files remote" can be simply making sure your ignore patterns are set how you want them, if that works for you.
Is it possible for a game to read two mice separately? Sure. It's not common, but it's possible.
The game "Lemmings" was ported everywhere in the early 1990s, but the original Amiga version supported two mice at the same time (two mice, two players, two cursors).
That's a rare example of a game that designed in some support for two mice, and that support was specific to one platform.
Woke up this morning feeling a bit damp but didn't connect the dots until the water had soaked through a couple of layers all the way to the mattress. Bum.

To be fair, that song is well over a decade old.
What's a reasonable minimum age for playing on an oldies station, do you reckon?
