I haven't been able to find this aywhere but on the desktop...
How can I reorder my artboards for export?
They seem to just be ordered in order of creation, and when I export I can choose which artboards to export, but not the order.
Agreed, it doesn't look like this is possible. You can move the artboards around in Ai for iPad, but they reorder themselves based on artboard name/number at export.
This would definitely be a useful feature, head over to the Illustrator Uservoice page and make the suggestion in the Illustrator (iPad) Feature Requests area.
Seconding this. This messed up my workflow with a client doc. Please add!
