I only use the normal mode, which I suppose is the folder mode.
I do not use tags.
I guess my answer increases the chance of the newest greatest OpenInkpot coming out soon!
By the way: do you know why OpenInkpot is more stable than the other firmwares? When I use the other firmwares I often get thrown out of books after reading a few pages.
Some say it is because of crappy batteries (I ordered an original Nokia battery to find out).
Is it because computer programmers from Russia are the best on Earth?
Those from Ukraine are very good too: the shortcuts and the precise dictionary searches with the virtual keyboard (short 4-key press) in the April LBook firmware are great.
