@sam_i_am It's really great. It allows you to view and edit documents directly in your browser with multiple users. Similar to GD.

@pkntl Oh that sounds perfect! I'll try this out today. Depending on the outcome, I may add it to a tutorial I'm working on regarding home networking (pi-hole + NordVPN access server + Nextcloud server). Thanks for the link!
