Sorry for the late reply, Mamesick. I wrote that feature in my frontend in a way that will read all plugin sub-folders and add to that TListView... there is no limit on how many plugins you can have there
Emu Loader goes thru all the sub-folders in the plugin folder and opens each plugin.json file to parse some info from them (title, name, version, author).
It's a simple code, but it's written in Delphi 7, not in C.
