How viable would that be? Can it also just run in the background like the actual app?

Would it be possible to run Syncthing in Termux?

I use Linkding too, it’s very light and it’s great, I only wish it had the exclude tag filter and no tag filter. That would make it perfect.

I’d lose that one day after buying it.

What are those?

Wouldn’t bet on it.

Find alternative… Modded Apollo, or Winston looks cool.
