Igniters, Here and there we see usability issues bubbling up in the discussion on @dev and @user list, Stackoverflow, etc. Looking at them I would say that the majority is pretty straightforward to fix bringing the overall usability to a better level.
Let’s keep using “usability” label for all of the features of this kind. All of them will be added to this filter that I suggest to add to your panel: https://issues.apache.org/jira/issues/?filter=12341720 <https://issues.apache.org/jira/issues/?filter=12341720> Most of them are easy to implement, so if you’re interested go ahead and assign any of them on yourself. — Denis
