Dont like the new ui
The custom theme screen seems to deselect your chosen background image every time one tries to adjust something - be sure to put that back on every time you mess with stuff or it defaults to white again. The box above it is the one that controls the main background colour, but it also forms the default for drop down boxes and so on, so no comfortable mid-shades if you want to read anything. Just takes a load of fiddling around, I think, alas.
Suspect there isn't a way to put the menu boxes back where they should be because everything's geared towards intelligent telephones these days, but if I'm wrong I'd sincerely like to know. Heh, my only non-desktop device is a secondhand iPad so old I can't see player login times for my own games on it no matter how much I tap or hover.
