Comment function for cards

[hx187]

Is your feature request related to a problem? Please describe.
If I am editing a card together with another person, I would like to write comments for that card. So that my colleague, among others, knows why there are current problems, etc.

Describe the solution you'd like
A comment function for each map. Best with the editor and the time stamp.

Describe alternatives you've considered
Alternatively, you could do it via the description field. However, this is very unattractive and makes no sense.
