While working with the Monitoring->Problems view, I really wish, we could exclude stuff we don’t want to see right now. There are alreday many filter built in, but they only work in AND mode and since 4.0 in OR mode if I recall correctly. 

But we don’t have the possibility to exclude certain information. 

For example: Sometimes I have so many active “Low disk space HDD events” that it’s hard to spot other important issues. In those moments I would like to set the Problem Name filter to NOT show any event with “Low disk” in its name.
