Current version 6 could be faster and with more search tools (i.e. to find a page to link)
Very easy to use. Can add specs and generate a MSWord documenting the specs.
Easy to learn and to use. Very powerful for online prototyping. Solid reusable components and styling. great support and lively community. Possibility for annotations. Weak points - not optimized for printed specification, very slow in collaboration mode
Excellent choice for wireframing of web pages!
Once you get over the default Comic Sans font (which you can change), this is an excellent, quick tool to sketch/prototype the "feel" of a design (as opposed to the look of it in say in Photoshop).
nice design, a lot of UIs and it so easy lo use, I like it
Prise en main très rapide, je suis pleinement satisfait.
