I installed the new firmware. No problems. Since I rarely use adobeviewer (not if I can help it) the new zoom levels don't really do much for me. The only new feature I do use is the double-click keymap option on the power button. Now, I can single-click it for the Last-10-read list, double click to lock (which won't accidentally unlock in my pocket), and long-press to shut down. Great. But in checking the keymapping options, I noticed a new one.
Question: What does profile do? I mapped it and tried using it and it seems to do nothing obvious in the main menu, the bookshelf, or inside FBReader or adobe viewer. Am I missing something?
