I still cannot post in feature request.
My collections are growing and I need to rearrange them so I can see them as group. It is not literal group, it is only in my head, when I see them near each other, I can easily treat them as group. With prefix perhaps, but I begin to use acronym for collection, cause context menu is not wide enough, and tooltip is too small.
It is too tiring, to scroll up and down in database collections.
In collection’s property, we can arrange them by dragging to suitable position for sequencing, may be, it is time to do the same for collections.
