Perhaps too much to ask, but it would be nice if the little red cross that appears top-left of a plate actually remained visible as you zoom in making easier and quicker to close a plate. At the moment, you have to zoom out manually to see the button which is in a fixed position.

Note: Zooming in and out has been a controversial subject lately, however the latest IOS 12 updates has reminded me how important equipment performance and task efficiency is to my flying, and how detrimental it can be when there any sort of delays especially during critical phases of flight. When the IOS 12 update caused the slow downs, having to swap plates on approach to an airfield during the final stages of flight was nearly impossible because of the steps involved to even close a plate (panning and zooming were unbearably slow). Having quick access to the button would have made it easier and the IOS changes less of a burden in that scenario.
