The ever fleeting 1.0 release remains elusive, but in the meantime there is a new version of DoWant.
This version is a relatively minor one, but introduces a feature that has bothered a non-zero number of people. You can now add images and sources without having first saved your new item.
Behind the scenes this is a pretty change. Previously, DoWant made a server call when you pressed the "save" button on the item, source, or image. This meant that you needed to have an item ID before being able to add an image or a source to an item. In 0.9.95, all the item data is stored locally until you press the "save" button and then it's sent to the server in one big bundle.
It's available on the downloads page, please let me know if you run into any issues with it.
thanks
