Thanks for the response,
Interesting that you have performance issues in PlexAeon but not in the default Plex skin. Both run about the same for me with at least 600 to 1200 files in multiple libraries (OC'd to 1K).
Plex client performance problems are best evaluated with a large library. In my own case I have nine library sections, the largest of which are "Movies" (1316 movies) and "TV Shows" (877 shows, each with varying number of episodes). I haven't even tried to count the number of media files in a long time, but an old estimate had it at appx 25,000 and the library has grown considerably since then.
I currently use similar overclocking as you do (1000, 500, 500, 6), but even so I always get less responsive GUI with the alternate skins than I get with the original skin, and PlexAeon is considerably worse than Night, both in responsiveness and in its tendency to crash when navigating my large library sections.
Np, I made time this morning to start up a new Ubuntu VM and get the dev environment going, so I'll just fork off and add it in to make updating easier for me in the future when using dev versions.
That's one way to do it, though it's significant overkill if you do it just to add skins.
For that I'd simply use the SMB interface, with a modified "samba.conf" file.
Start by enabling the SMB server in the services part of the "RasPlex Settings" menu.
Then go to your Windows PC and open a normal 'Explorer' window, and edit the folder path string to be the LAN IP address of your RPi, but preceded by two backslashes, like "\\192.168.10.120" though without the quotes. That's the address of my own RPi in my LAN, though yours will of course be different. But if you don't recall what yours is, just check it in the "Connections" part of "RasPlex Settings".
Once the Explorer window shows the list of shared folders from your RPi, doubleclick the folder named "Configfiles" so that it opens in the window. In that folder you should see a file named "samba.conf.sample" which contains a list of the already defined shares, so this is useful as basis for a new "samba.conf". Using the right mouse button, drag-drop that file to another position in the same window, and choose "Copy here" in the popup that appears. (NB: You might get a security warning too, depending on your windows version. If so, just click that away...) This copying should create a file named "samba.conf - Copy.sample" or similar (that's for Win7), which you then rename to just "samba.conf".
Now you can use a text editor on your Windows system to edit that file. This should be an editor which recognizes Unix-type line endings, and preserves them in saving. With that editor you can then insert the following text block:
[-_PHT Addons]
path = /storage/.plexht/addons
available = yes
browsable = yes
public = yes
writable = yes
root preexec = mkdir -p /storage/.plexht/addons
A suitable position for this text block is either at the bottom of the text file, or between two of the existing similar blocks.
After saving that file and closing the Explorer Window you can now go back to the RPi and again enter the "Services" part of the "RasPlex Settings" menu, where you first disable and then again enable the SMB server. This will cause the newly created "samba.conf" file to be used, so that the shared folder "-_PHT_Addons" will be displayed topmost the next time you open an Explorer window for your RPi fileshares. And that folder is where you can place your alternate skin folders in order for RasPlex to recognize them (though that recognition will require a reboot).
This preparation of the samba.conf file is something you only need do once per RasPlex install, and thereafter you can freely install, update and modify its alternate skins as you please, doing all the work through Windows. Well, almost anyway. You should always avoid making modifications to the skin that is currently in use, as the effects of doing so are unpredictable. So when you do want to modify a skin you should first make sure that RasPlex is set to use another skin.
For even more convenient access you can also make a folder shortcut for that shared folder, and place that on your desktop.
This way you can always reach the addons folder of your RPi for skin modification just by double-clicking that shortcut.
