@SonoMichele Hello there! Honestly my most used services are for document collaboration:
- Overleaf (https://github.com/overleaf/overleaf)
- Hedgedoc (https://hedgedoc.org/)
I've recently started taking advantage of file syncing again through Nextcloud. Though I usually bounce around on that front between not syncing at all and using Syncthing.
How about you? What's your favorite service?
