Hi, I rather doubt that you need another opinion but here it comes. (Actually three opinions :-)
1. Please don't add any buttons (whatever they are called) to the dialogs (and remove the existing new "help" buttons) It makes the dialog bigger and more complex; moreover, I can't imagine a user that needs a per-dialog tooltip setting; finally, you can add tooltips without having to redesign the dialogs (safer, easier) 2. Add an option to the preferences dialog with "full" tooltips activated. -> Newbies will get full support, experts can deactivate them with just a few strokes once for the whole life-time. 3. Tooltips that repeat what is already listed in the dialog are useless - agreed. However, a default tooltip "No info available" would be nice because sometimes you are not sure whether there is really no info or you just did not hit the right spot with the mouse. Michael
