I could really use an Auto Trace feature in Designer. I hand draw pretty complicated illustrations which clients often want to have as a vector so they can be scaled up to be big vinyl installation murals. It's kept me bound to using Illustrator as I can't find a third party software that converts the bitmap line art in the way I want. I need to have the black lines traced AND the white areas so that they can be selected and coloured in Designer. In Illustrator I select Live Trace then make and expand to do this. I've tried Inkscape but unless I'm missing something, can't find a way of doing it. I just get the black line art converted and the white areas change to transparent and can't select and colour them. It's driving me a bit mad TBH.
I've included a typical illustration here as an example of the bitmap line work and the results I'm after.
