kartu, I really like your work. Immediately after buying my 650 I installed your firmware. Your firmware, with folder and apps support, was one important reason for me to buy the Sony Reader
I don't use the latest version (because of the advice to wait), but one version earlier which has a few translation errors in the German language. I don't know if they are fixed in the latest release, but maybe I can assist in improving the German translation. Is there a public file to participate?
I also like the feature to assign custom actions to the buttons. Could you add more custom actions we can select from? Like "Entering Note editing mode" and "Zoom in"
And maybe a hotkey to temporarily disable the touchscreen?
