I would like to be able to have a canvas which I could use to build a visual designer, for things such as flow diagrams, etc. With the ability to have a data-driven palette of icons/images/symbolic representations that could be dragged into place and connected by lines, this would be a great tool!
You do have dhtmlxGantt, so it seems that it would be possible to do this
Do you think you could have this done by next week? (just joking )
