I would love the fact to redefine buttons for my Cybook
Gen3.
I do not see the sense in a delete-button since installing books requires a pc anyways, since I do not listen to music the same applies to the music and volume-buttons.
I would on the other hand love to be able to use these buttons for dictionary-lookup, bookmarks(add, remove, next, prev), increase, decrease textsize, zoom +/- in pdfs etc, etc and I would like to be able to define them myself - in some books I might need to add bookmarks often and switch between them, in other books I might need lookups, etc.
I would be perfect to have a (definable) default setting and the possibility to spezify alternate settings for special books, but for the beginning being able to change the settings globaly would make me happy.
