Honeybar, Diceplayer & aspect ratios
So I also tried Honeybar with my brand spanking p6800 (ZSLA2 Hong Kong firmware) and confirm it effectively hides the status bar in all the places/apps I've tried it so far: Diceplayer, stock browser, gallery & home screen. If I discover somewhere it doesn't work I'll advise but so far so good. No issues at all un-hiding the bar - just tap the invisible spot bottom centre edge of screen.
Most useful usage for me - for web-browsing where screen space is at a premium. Easily worth the $1 for that alone.
I was actually most interested in it for use with video, and it certainly works as intended there but for me the effect was very subtle:
(i) hiding the already virtually invisible "movie mode" blacked out status bar with its tiny dark grey function locator dots (bar is of course more visible in a pitch black room, so more benefit there); and
(ii) as it frees up the space used by the status bar the video image is theoretically able to "expand" to occupy that space. No doubt this is a great benefit for those who like fill the frame or have 1.6:1 source material. But for me much of my sources are 16:9 and I prefer to run in native aspect i.e. black bars above and below the image. So in this case all hiding the status bar achieved was move to the video frame very slightly down the screen (without changing its aspect, or raw pixel width or height) so that the video image remained centered between the upper and lower bounds of the now slightly increased vertical accessible screen area.
Probably a bit too much detail there but hopefully useful for someone.
PS: currently flicking through a 7.5Mb/s rip of episode one from my Bluray box set of BBC Frozen Planet and it is... stunning.
