add search functions
add bookmarks (the bookshelf) : perhaps write a separate application for handling bookmarks
[DONE] redesign the app to function with bundles, so we could have bundles for loading .gsdoc, .html, man or texinfo files ...
(re)add links ...
add references
add a better printing support
add mng support -- so we could have animated help files... a program to create mng from screen actions would be good too :)
correct bugs !
