What would be really useful, would be to start it when scrolling or dragging start, and ending it when it ends. I'm thinking about the usage while reading and scrolling pdfs (e.g. on ezPdf)
Since I cannot avoid those automatic deactivations of NoRefresh by the system, this may be useful.
I've just implemented it, so now when you launch the app and it is already running, it will activate NoRefresh mode. So you can just use a shortcut to the app using NookTouchTools to activate.
I will add it to the first page post.

Hi, again!
-Your last update made your app really useful!
-Still is it possible for app find out what is the current refreshing mode and toggle it when launched?
-is it possible to maybe create another app that would only do single refresh. sometimes it would be enough and maybe even more useful that proposed toggle version above. e.g. you what to see what is on the picture in web browser so you do one refresh, or e.g. you want to get rid of some really anoing ghost - you do one refresh
(Now it seems only to start no-refresh mode but you have to restart app you're using (e.g. opera when you what to see clearly what is on the selected picture) in order to dislable no-refresh mode.)
thx
Ok, I've got the toggle via shortcut to work. However, I'm using logcat to determine current refresh mode and I'm not certain this approach will always work. Please test and report any problems.
I will update first page post.
- would be nice to create one version without any gesture activation, since I do not see almost any point for using it. I have visible status bar with small book on the left always which i use for running your hack.
- putting somehow some extra buttons into status bar should also provide more use to your hack. One for toggle and the other for instant refresh or some automatic refresh hack..
- your effort took nook another step closer to low power, eye-friendly tablet. Last missing thing, since keyboard and usb flash memory are now also working (depelopment forum - usb host), is usb mouse. ))
thx!

- If there was someone that could make your app be always on or always off regardless, what one do on nook... would be great.
- One almost wonder whether, with some contrast-brightness settings, could watch video - like youtube or vlc maybe
you mean using this trick to support gray when in no-refresh mode? Would be great. This nook st look like its gonna be grey-scale tablet after all.Excellent job! I was wondering whether the OpenGL acceleration in the Nook Touch could be exploited: use a fragment shader to dither the display before the EPD gets its mucky hands on it
Unfortunately this is way over my head and I can't get past the initial idea.
eg http://stackoverflow.com/questions/8032006/glsl-gif-dither-effect-optimization
Going by appearances when you turn it on with images on the page, I think the (severe) ghosting when it's first enabled is that pixels that were a shade of gray (due to antialiasing) are not refreshed in this mode, only black/white transitions update properly. That's why once it's been on for a bit (and all these pixels have been replaced at least once), the ghosting clears up.
So would it be possible to flash the whole screen to solid white (or black) when first turn NoRefresh mode on, so those first transitions all start at one extreme? Maybe by just taking the dummy view you use to sense touches and temporarily drawing on it?
Great; that fixed the antialiasing ghosts as I hoped it might, though there's still slight ghosting of the letters that can be cleared by "scrubbing" the scrolling over it. OTOH, looking closely, I think it's not that those ghosts get any lighter, it's that the rest of the background gets dirtier (e.g., the whole contrast deteriorates a bit). So a black flash might leave less ghosting (taking the hit right away on every pixel), but is also more initially distracting (and an initially worse image). Or it might turn out that that just leaves negative ghosts (e.g. the A2 black isn't as dark either). Six of one, half dozen of the other; this is probably as good as it gets
Also, I see a minor (and maybe easy) bug; the button you used to flash white seems to have a border around it, which gets left as a ghost around the screen and gradually broken away as characters pass over it (just like antialias grays did before). At least it's only at the very edge of the screen now.
But this is very usable, thanks so much! Before it was hard to clear up if there wasn't anything black nearby to drag through the ghost.
Hi!
-your app is nice!
-however i have sometimes problem with unexpected deactivation of norefresh. is there any chance of using nook touch tools of color tools to map for example small book icon on the top-left to start your app and toggle the no-refresh?
thx
