[Feature Request] Screensaver interval settings

Thank you for your great work!

One of the most favored features in contrast to the official Plex clients is the screensaver in combination with fanart. Sometimes I start openPHT just to show the screensaver with the movie background images in my living room.

Unfortunately the interval is fixed, the pictures change every 15 seconds. This intervall is often too short, too hectic for me. So I would be very happy to be able to set the interval to values like 15, 30, 60 or 120 seconds. Could you please implement this feature?

Many thanks in advance!

Piggybacking onto this request, may I also make a similar request? Please add the ability to show a screensaver if the movie/tvshow/etc is paused for more than a minute, instead of just having the option to dim the screen. I have a plasma TV that suffers from image retention and sometimes I get up to go to the bathroom or whatever during the movie and I would love to have this feature, thanks!
