If you’re into using Javascript toolsets, then you surely have to take a look at Qutensil, shortly referred to as “Q.js.” The reason? Well, according to its official page, this toolset “was developed from dissatisfaction with the existing toolsets.”
Good, so what’s so special about it? “Not that there aren’t any good styled sliders or color pickers out there, but there is no library combining them all in one system,” or at least that’s what the team behind it says. Here’s a quick features list: growl-like user messaging system, raphaël-based color picker, slider, tooltip system, draggable window and alert / confirm / prompt windowing system. Not bad at all, don’t you think?
Using a dynamic stylesheet system able to generate the CSS declarations on demand, but only for the modules active at that time, Qutensil is free only for personal use, and requires Prototype.js and Scriptaculous to work properly.
Compatibility: Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 7.0+. Internet Explorer 6 and lower are not supported and won’t get support in the future, either.
