Please add icons/emoji per calendar
In addition to calendar colors, please also add the ability to add an icon/emoji per calendar that shows up next to each event. I consult and have many calendars (as I'm sure many OneCalendar users do), and I'd like to keep all business calendars as one color, and all personal calendars as another color while still being able to distinguish between the subgroups (per company). This seems like a low cost feature with huge benefits for some users.
