Needs keyboard shortcuts for the tools... there's no way to drag nodes, etc. around unless you stop and access the toolbar. Also, it's very cumbersome that you have to access the select tool to select a node then go back once again to the toolbar to select the grab tool to actually move it. The grab tool should also act as a select tool. Note that if you try to use the rotate tool, you can't drag it... it rotates in increments by clicking repeatedly. But, hey.. it's free.. so, whatever.... thanks for making this!
