it should provide basic configuration like which tab(s) is (are) currently opened...

Offline version. If internet connectivity is poor, or even non-existent, e.g. on a train or a plane, I can't use it.

Please enable cloning of layers! Would also partly fix the problem with cloning pages.

I really like the new feature that every page has a default local layer now. My global layer list is a lot more organized. But because this layer is local, you can't use its content any more to create variants of the page (e.g. with data changed, dialog boxes on top etc.). The next logical step would be to support variants of a page, each variant with one local sub layer. When specifying a target, you also could select the variant to jump to :)

want to redesign a website, but dont want to prototype it from the skatch

I am missing the possibility to describe modern interactive application sites without changing the page (via AJAX etc.).

The given options of "drawing an alert box" is definitily not enough. One way would be to be able to activate/deaktivate described layers on a page in the clckdummy, based on the users actions (for example by clicking on a link).

The word export is great, but the generated file is not usable, since too heavy. I have a prototype with 7 pages and get a word with almost 90 pages. Wow. That is heavy. For example I don't need all the layers in the word file.

as it is only possible to change the font size it would be great if you would add several features to change the style of the font e.g. family, color etc.

At the momen I see if someone else is working on a usecase or page. I can't see who and I can't contact him/her. A Livechat on the prototype would be great.

It would be nice if tabs, frames, rectangles, etc. supported background colors. It would be even better if the sktch-mode rendering of the colors supported the same hand-drawn style as other stencils ie. a chalk-like scribble of color.

grab UI elements, support both orientations, etc..

Although rich text has these capabilities, it really doesn't work very well (often it ignores your request, or extends it to the entire stencil).

Simply *bold* and _underline_ facilities would make these regularly-used formats extremely handy!

Provide movable guide lines (auxiliary lines) to help align elements more easily.
