Thanks @Stephan, I appreciate your kind response even in the face of some of the bad news I delivered! 🙂
Your voting on that feature is greatly appreciated – genuinely; we take the features list seriously and often roll in features there based on votes and activity, so it’s definitely the best avenue for having your voice heard on this topic.
Vote up that feature and watch for updates to Filter Bar – every update comes with a changelog of the list of changes in the update, and so if anything like this makes it into a specific update, it will be listed there!
Best of luck with your sites and projects in the meantime.
Cheers!
George
