1. At the moment there is no need for a fixture builder as our library department responds within a couple of days, so if you find anything missing or has wrong values, you may send us a relevant email at library@capture.se and we will take care of it.
2. Not sure I follow. But have you tried having the universes window (Window->Universes...) next to your working view?
3. There is no such tool present at the moment but you may request this to our dedicated Feature Request forum. In the meantime, you may use the Recent category found on the Library tab if that helps your workflow.
