- Day and Month unit is in my backlog but every low in priority as this plugin is quite niche and it already had most of essential features for my setup. There is another plugin based on this one but developed by a different person that does support day/month https://discourse.joplinapp.org/t/plugin-event-calendar . I haven't try it myself but it may suit your need.
- The week events in order of written so that you can manual "set" the event will appear in the calendar for weeks that have more than one event. As I am too lazy to implement a proper a visual-order I keep it like that. I can see how it is troublesome for certain way of writing. I will consider this problem the next time I work on this plugin
- Separating events and periods makes the logics simpler. Combine them may introduce new problem so this will unlikely be changed.
- Repeated events is a good feature but it can be a little elaborated to implement so I am not gonna implement it anytime soon.
