Maybe not top priority, but here it comes for the records anyway...
We have several cases where the possibility to "invert" a displayed list from the frontend would be handy. Example: Somebody planning a patrol mission may want to see all potential crew members that has a certain competence. But the training coordinator want to see those who lack this competence. A single list would serve both if there was an Invert-button or checkbox at the top.
Yes, creating two lists is of course the workaround that we are using. But the number of list grows quite large and usability of the site would improve if we could cut down on the lists.
