Keen for this too 
Love being able to open/shut plex with my Harmony.
Any update on this @tobiashieta ?
I used this quite a bit (to launch PHT). Super disappointing that this doesnāt work in PMP. My Mac Mini is the dedicated PMP on the television and runs without a keyboard or mouse attached. Once PMP is exited (happens more often than Iād like), thereās no recourse but to connect a keyboard & mouse, remotely connect from another computer (reboot the system or launch the application from a remote desktop session). Pretty inconvenient. I really hope this can be fixed soon, sounds like itās way overdue at this point.

Itās part of 1.1
Really need this functionality, please see my earlier response.
@tobiashieta any update here?
Installed Plex Media Player and start with long press Menu now doesnāt work for neither Plex Home Theater nor Plex Media Playerā¦ what do you suggest to stop me going backwards?
@siknus Start Plex Home Theater via menu once. Shut down PHT and try to start with Apple Remote again. Does that work?

It works, thank you! At least I can use Plex Home Theater again. Now Iāll have to wait until the option to start PMP via Apple Remote is implementedā¦ 
Has anybody got a work around for this if itās not in PMP?
What a joke PMP is.
I just switched from OpenPHT to Plex Media Player (UNO) ā¦
And I canāt figure out how to get PMP to launch via my remotes (using an Apple Remote or a Harmony remote paired to a MacMini via Bluetooth or emulating an Apple Remote)ā¦
Clicking āmenuā worked on the old Plex Home Theater, and on OpenPHT, and on Kodiā¦ But not PMP.
Is it still just an āupcoming featureā on PMP after all these years, or is there a different command I should be mapping to?
Digging through the forums I see various workaround solutions involving third-party software, but Iād rather not run another program just to get a single key to work haha.
Hard to believe this hasnāt been implemented yet, so Iām hoping Iām just overlooking a more current, simple solution.
(Update: I donāt think this will help with a basic Apple Remote, but this Apple Automator guide is a pretty fast/simple solution for assigning a keyboard shortcut to launch any app; and then with a remote like Harmony you can assign that keyboard shortcut to a button on the remote. I tried it, it works. But, yeah, it still seems like this is pretty basic remote-control functionality Plex should support āout of the box,ā rather than sending users off on a hunt for custom solutions. But at least there are some workarounds of sorts, for some remotes anyway: https://m.wikihow.com/Set-a-Keyboard-Shortcut-to-Open-Mac-Apps)
