just installed it. according to release note should be a lot good changes. esp. the web browser is usable now.
But I notice PB responses slower.
The big issue for me now is the theme. Default theme is contrast, which may good for grandpa/grandma. I tried to install new ones, e.g. Cristal-Themes.zip from SIRSteiner https://www.mobileread.com/forums/sho...d.php?t=188665
also fred from http://www.the-ebook.org/forum/viewtopic.php?t=11679
But all not working for me.
The main screen is blocked(or covered) by 4 frames of window. Any click not working!
as read from google translated
old themes are not supported.
