I propose to add a search functionality just for groups (unfortunately my Java knowledge is nearly non-existent, so I can only propose this, but not contribute). For large databases with many groups (I have >900 groups) it is a bit of a hassle having to scroll to the group of interest. It would be nice to have a search feature (similar to what is already available articles) just for groups. When searching for a group you could then immediately hop to the group of interest, instead of having to scroll to it.
