Dear Plex programmers,
Adding a general variable to specify the time (seconds) for a slide show requires 1 line of code.
Reading that variable every time when a slide show starts requires another line of code.
So, for a basic improvement two lines of code are necessary (okay, you’ll need something more to define it as an input value in a user interface)
Adding more features like “arrow up = + 1 sec, arrow down = - 1 sec” and store the last delay value in a variable for every single mediathek will make it a bit more complex…
Nonetheless, it’s no big deal 
So PLEASE get it done!
