I love Cryptomator for it’s simplicity and security and use it now over 3 years. With Cryptomator Hub im even more hyped. When I use Nextcloud or other cloud platforms I love the file versioning feature. So I hope Cryptomator can implement something like this. A simple workaround solution would be to see where the certain file is encrypted stored so I can use native tools from Nextcloud etc. This is in my opinion the better solution then an native build in Version control system. Cryptomator works great but I always get a bit stressed when I don’t know where a encrypted file is stored, when such a feature would be available it would also be possible to encrypted just one file. Also maybe for collaboration you can encrypted a citrine file with multiple keys.
