I tricked you, because there are two suggestions in this post
First, it would be nice to have the export route saved in the .capx/.caproj, so I dont need to search the same directory every time I have to export (many times a day).
Secondly. Why in the world the group collapsed property is saved in the .xml (not the uistate)? It becomes really annoying seeing diffs where the only change is a collapsed="1"
