I have just installed the fw 4.12.12111 and added some new patches I didnīt have before:
Enable rotation on all devices: It works, but when you rotate to landscape, you only can turn pages. Yo cannot select any menu item (including coming back to portrait!

) and you cannot connect to the PC (you cannot confirm the question about connection yes/no!). Here I started to be very afraid

that I have to full reset the ereader (I had no way to put another patch), but switching OFF and ON the ereader, luckly it returns to the menu in portrait position

. Then, you can patch again to remove this option ... What a pity ...
Note: I have an H2O Ed2 v1
Always show confirmation dialog before upgrading: I have had no posibility to check it, as I already updated the firmware before patching. See next time.
Freedom to advanced fonts control: Very nice patch (I do not know why I did not install it before)
The patch I used for fixed epub margins, now (with the last change by geoffr) still leaves a bottom margin bigger than expected, while the top looks to be less "big".
The other patches seems to work as before.
