I discovered the various Rockbox simulators and am now using one for my Sansa Fuze v2. I think it has a bug or two, but overall it's making theming much easier than loading and testing themes on the device itself.
One question, though: Is there a quick way to reload the current theme? I make changes, test, change, test. Each time I have to get back to the Main Menu, Settings, Theme Settings, Browse Theme Files, scroll, select. Then back to the WPS, And much of the time I break something and end up looking at the default WPS and have to repeat all of the above again.
I read somewhere in either the manual or wiki saying that 'playing' a theme will load it, but I'm not sure what that means, or if it would be any quicker. A hotkey like Ctrl-R to reload a theme would be ideal. Does such a thing exist?
