I have downloaded and installed the latest firmware; however I think there's still much to do; let me list the missing parts from my point of view:
1. The default zoom level in .txt files is still 3 level (two normal one landscape mode); however this format is the basis of all formats before conversion and it's very easy to use. Therefore I believe that a 5 level zoom like in pdf's is necessary.
2. I think to be able to change the font type
during reading would be perfect; without going back and forth between settings etc.
3. I am happy with the time and date support; however it's not displayed during reading with pdf or txt files. I think a small status bar showing the date - time, page number and battery condition would be perfect.
4. By the way I have just realized that the date and time is reset with shutdown which makes this update funny at least
) I always shut down my device for good battery life, like I believe as many people do the same. The reset of the date and time with shutdown is very funny.
So far these are my findings.
Regards.
