In the monthly view, in the top right corner of the “Daily” section, days with notes are marked with a small dot, which I think is a good feature.
However, it would be much more important to me if days with appointments were marked (e.g., with a different colored dot) or highlighted in some other way.
That would make it much easier for me to jump directly to relevant days in this nice overview without having to search for the appointments first.
The iPhone’s Calendar app, for example, offers this feature. However, I don’t want to have to switch between different calendar apps; I’d rather use Opus One consistently.
Thanks a lot and best regards
