Thanks for the feedback, Willh. :o)
The naming of elements is a good practice, but I know—in the heat of a project, it doesn’t last very long, even with the best intentions to keep going.
If you do not use Layers at all, you could drag one of the active onto a new Layer… but I guess this not really cutting it. ;o) Then filter the per Layer.
I like the Select>>Selection-Filter> Create Selection Object. It works not with tags initially, but once you have a Selection Object, you can drag and delete anything in that list. As it is indepentend from all other options, e.g., Layers, it is kind of a private list on top of everything, and stores a previous selected group.
Besides that, I guess the only option would be: http://www.maxon.net/support/suggestions.html
The “Show First Active” could have a variation: “Show Only Active”.
My best wishes
