sometimes when I put comment to some task I need to mention all collaborators. The reason is simple. When some of my colleague have full archiv of a new notifications, they just archive notification when they do not see their name mentioned. I would like to use it for important comment. When task has 4 collaborators or more it is a little bit annoying to mention all of them. Are you planing implementation of function something like @collaborators which will be indication for all collaborators that this comment is important to read it with attention?
