The new UI seems to have forgotten tables and panels.
I have a custom field for Acceptance Criteria and use tables and panels to organize the contents.
I had it nicely set up then the new UI arrived (with no warning I might say). Now I cannot edit my tables easily, cannot find out how to add a new panel.
I might say that I used to 'code' everything exactly how I wanted/needed it, then you made it point and click and now I don't even know how to do that.
