Like it.. so decided to flash the V3 instead of using the live version.
Nice
Couple of notes though:
Bug: When adding bookmarks and you want to delete them: It's not possible to delete the last one
Annoying: No option to specify the default reader. It's nice that the press number a couple of secs gives you the option, but I would like the option to change the default reader. Preferably in the bookshelf menu.
Helpfull: Would be nice to have a context aware help page/menu item that shows the options available per reader/bookshelf. There are so many options and they slightly differ per reader that it would help as a reminder.
The recently read folder from the original firmware is something I noticed is very welcome for madshelf as well. Especially if you have a lot of files and folders it saves some searching.
