It turns out this was mostly a false alarm. Sorry for making an issue
out of it. Last night I made the leap and upgraded all 5 production
myth boxes to 0.22. With my reasonably powerful master backend (Core
2 Duo E5200) and a reasonably weak frontend (IONITX-C), bringing up
the Recordings page with almost 1000 recordings is pretty much as fast
as in 0.21, about 2-3 seconds.
I still wish I could get some visual feedback during this 2-3 seconds.
It seems like changing the button background image after it is pushed
would be good feedback. But I haven't managed to see any effect of
entering the "pushed" state. I tried adding something like the
following to the mythuitheme.mainmenu.menu.buttonitem section of
to try to make the background disappear whenever a menu button is
pressed, but nothing happens. Is the "pushed" state supported? Are
there any known working examples in some theme?
