Linux user interface design tools

Trying to come up with a good user interface is not an easy task. But I need to. And what could I use on Linux so I could make suggestions for the improvement of a web app’s user interface?

Some of you might be dependent on things like Photoshop or Illustrator — maybe even Powerpoint — to convey your message. As for me, I personally prefer it lo-fi: pencil and paper! But there are times that it simply isn’t enough so I am looking for other means to do that.

In terms of creating wireframes, Denim would work, I think. You could just indicate the main sections on the page, where the links are, and even create a site map for your reference. But there’s one drawback: you can’t always show all the interactions you want, especially for those funky inline AJAX or Javascript magic.

I find the GIMP a bit difficult to use when it comes to graphical mock-ups. Maybe the combination of the wireframes from Denim and CSS editing via the Firefox web developer toolbar might do the trick so that your teammates could easily visualize the colors of the page.

I am still looking for other options. But right now, these are the ones that seem feasible to use for me.
