If anyone add a comment or changes card's name/description/attachment/date or anything related to this particular card I'd like to have this card highlighted for some period of time or until I open it and thus mark it as read.
I know there are notifications but in complicated boards it can get quite messy. Also I know there are rules, for example you can make rule that adds let's say purple label whenever card is changed, but the label doesn't disappear until someone removes it manually.
Is such feature built in Trello?
