Add description field

[yassirnajmaoui]

It is very useful to have a description field in the events that would be displayed in the interface.

I think it would be useful for, for example, adding addresses to events or some extra info.

Hello, kindly implement this change.. this would help speed up when working with the calendar. I often take note and i must every time click "Open note".. it takes time. Please consider adding a textarea as a quick way to add small note (instead of clicking "Open note").

Thank you!
