Paola, thank you for testing. Please don't continue testing the old version. I have a new version. I will try to upload it this evening.

1. set rotation to 90 gives landscape mode (not 180)

Intended behaviour was that if you tap on "set rotation 90" the portrait mode will be activated and the text changes to "set rotation 180". The text describes the command that will be executed, rather than the current state. I think this corresponds to what you are reporting. You are right, the text is ambiguous. Anyway, I did it in another way in the new version

2. calling "X" from kobo menu 2 hangs the reader (but I guess this is normal)

This is solved in the new version.

3. changing the sort order of books in "books" view in the library hangs the reader; calling the library "books" sometimes hangs the reader;

Did not happen to me yet with the new version. I don't think I tried changing the sort order in the old version. I remember that with 2.6.1, when I copied a punch of books (200 or so) to the reader, I had problems using the books view of the library. But after some time everything went smooth. I thought that this might be connected to some problems with the creation of the cover images. Maybe this is also happening in your case. But I don't know. It could also be on account of how the old version interacts with the file monitor [and Kobo launcher] (I have changed this in the new version).

4. on the mini, the landscape mode is not displayed correctly (some rows are only partially visible). However kepubs read beautifully, and so do footnotes. some screenshots are attached.

This is the same on the Touch. The graphical interface is not designed to be use in landscape. One could possibly improve this a little by modifying libnickel, but one would have to do this for every new update of the FW. Thank you for the screenshots.

5. uninstalling: after the disconnection there was a quick reboot, and then the standard home screen appeared.

I am not sure about the quick reboot. There should have been a short "processing content". The rest is as expected.

Tried to browse the library, and the reader hung;

This is possibly not directly connected to the unistall process, but related to what you describe in point 3.

soft reset, and then yyour menu reappeared. I "installed the update", the device restarted, and all seems to be working fine -

This how it is designed. For any update process to start, you have to restart the device. I did it in this way, because otherwise in order to control the installation of updates, I would also need to insert a menu after each usb disconnection.

however the "exit" png file does not disappear.

I do not remove anything that is accessible on the user partition. The user has to delete the exit.png and .kobo/kbmenu [and has the chance to preserve some files she is interested in, eg. bash scripts she has modified in order to customize the submenu]. (This will not change with the new version)

Thank you again for testing.
