Wow, this is very cool! I just came across what you've been doing here. I'm very keen on using spreadsheets to assist with my HIVE blogging as well. I mainly use Google Sheets at present, but I intend to move to using Collabora, self-hosted under Nextcloud, on a Raspberry Pi device running the YunoHost distro of Debian GNU/Linux. In fact, that is the main thrust of my own HIVE blog, is setting up my new Raspberry Pi #homelab.
Take a look at what I was doing with spreadsheets on the social blockchain back in 2018. I'm starting to experiment more in this area now that I have returned to the social blockchain this year. I'll definitely be looking through your posts on this subject, to see if there is anything that I can glean from your Micro$oft way of doing things. Thanks for sharing!
