I also was using it for a while to log issues with my sleep where I deal with insomnia, so I logged how well I slept, how many times I woke up, how long it took me to fall asleep etc. That was a simple form I created using drag/drop in Baserow and called by a URL.
OpenVSCode server - makes editing my Homepage (above) yaml and my docker-compose files a breeze! It’s especially nice when you edit it something and it auto saves almost instantly. Makes some of my services change in real-time!
