First of all, kudos for the great journaling app. I've been on the lookout for different journaling apps that would be multi-platform and synced, and Diarium seems awesome in that regard.
Now, the feature request that I have is to add macOs and iOS widgets. What I would love to see is the On This Day widget, but of course, having other options, like a Quick Entry widget could also be nice. Coming from DayOne and Journey, I really miss this possibility.
Diarium version: 2.8.5
OS + version: macOS 11.6, iOS 15.1
