When users are concentrated on drawing a path (and at the same time are exploring different keyboard shortcuts) they will pay few attention to changes in the tool options. Instead, they will give their attention to the image area, here especially to cursor feedback (and hopefully the status line!). The major problem I see here is that when pressing CTRL (Design mode) while the mouse is not located over the path, there is no interaction possible (which is shown by the concerning icon). But there is no hint in the status bar WHY interaction is not possible. I'm not sure about the actual text, but maybe something like 'Move the mouse pointer over the path to edit it'(?) would be helpful and support exploration. > Basically it is impossible to really compare the path tool in 1.2 and > the path tool in 2.0.

I tried the 1.2 path tool, and was not happy with it. Nevertheless, on the first look, four modes seem to be more intuitive than three, as they hide les information from the users. Four buttons, combined with simple keyboard shortcuts for a quick navigation, are very easy to learn. But when I read this mail, I just realised that the tool is way more complex than it seemed to be on the first look, and that simple keyboard shortcuts are not realisable. > Given the prerequisite, that the whole tool should be usable without > having to move the mouse back and forth to a buttonbar (jimmac already > wrote about this) and the need for a modifier (SHIFT) we have two > modifiers left, which lead to the three modes of the existing tool.

I just didn't realise that there is such a lot of functionality. Further below, you said that the path tool is not for newbies, but for people who will use it on a regular basis and willing to invest some effort to study it. I know it's a bit sobering, but studies on help/manual usage showed that only very very few people actually read manuals. That's why an intuitive and easy to learn interaction design is so important! I admit that my suggestions were short-sighted, I just did not know about the whole complexity! but still I think that especially users who are not image manipulation experts need a bit more support with respect to the path tool. Especially, a hint on how to remove path segments and points is missing. Maybe at least provide a tooltip text for the three modes (Design: 'Create new anchors and shape the path', Edit: 'Add [Ctrl] and remove [Ctrl-shift] elements' - rough wording). > So, if you propose to add a fourth mode please also propose a way to get > out of the dilemma explained above.

Yes, I understand now - really complicated stuff.... 8-) But nevertheless, I hope you don't mind if I think of it some more, talk to some colleagues... not to change the conception of the tool, but maybe to find some very small and simple solutions to facilitate the learning. Have a nice day 8-) /ellen -- ______________________________________________________ Ellen Reitmayr email: [EMAIL PROTECTED] Usability Engineer mobil: +49.177.3325867 relevantive AG fon: +49.30.23455630 Zehdenicker Str. 21 fax: +49.30.23455639 10119 Berlin web: www.relevantive.de _______________________________________________________
