Most of us use large monitors today and run a browser app in less than 100% zoon. This provides lots of real estate on the monitor to improve an experience.
It would be great to have the height of this panel increased to support larger monitor resolutions. I realize in smaller form factors, a user would not want to have outer and inner page scrolling (two scrollbars), but I think there is lots of room to yield more rows shown in the panel at once.
I realize I could embed this control on a confluence page and increase the height there but we prefer using the hierarchy for jira page natively to use the tool. From an iframe, I can run this at 1700 wide by 1000 high which yields a great experience.
