At the very least please fix #3. I still have to remember how it works every time and teaching others. I always get asked "why" qlik did it that way. #1 was used a lot in QV & #2 is needed especially when there are a lot of variable in an app. 4&5 are nice to have's for me.
Thanks for all the feedback, a new variable UI is most likely going to shipped before Christmas (SaaS), client managed the following release February 2022. Improvements include search, multi delete, duplicate (sort coming later).
