Yep, just edit the value in the default.js file. I plan to make this configurable too, like the display color.
When I did that (admittedly, several versions ago, not lately), I could increase the speed of the updates, but it was still not fast enough for my tastes. There seemed to be an upper limit to the refresh speed, about 1 per second.
I was hoping to get the speed up to about four per second so that remote menu operations felt more realistic.
Is this possible to do, or is it a limit due to the frequency that the PNG graphic on the player is updated? How does that work?
