Having a simple refresh button and/or ability to press F5 to refresh/reload the current page on Plex Media Player could be a nice addition.
There are times when I am browsing my media collection or searching for a movie/episode and the page either half loads, or doesn’t load at all - a quick F5 will quickly fix this, and avoid having to go back, then re-do your last task.
My second feature request is a forward button, exactly the same as an internet browser, we have a back button and a forward button for the times you press back one too many times.
