this should be a user preference, saved for each user. should include any custom properties that are added by the user, too. should be for all of the main qmc pages/objects, but especially Users, Data Connections and Streams!
Hi @daudballing coming back to you as part of this idea. Sorry that the idea has not been updated earlier but this has been delivered already earlier this year with even more capabilities as you can define your own "bookmarks" in the QMC which are allowing you to see the columns you want to see with a pre-defined filter on top of it as well. Please let us know if you have any other questions in regards to that capability.
