I have slowly been adding better support for serialization. There are quite a few features that don't have full serialization support yet, so I have been adding that in. My motivation for this is so that I can have a reference part to use for coding boolean operations. It is much easier, and faster, to just have a file that is opened instead of re-creating the part each and every time.
The next three weeks are going to be crazy busy with my job, so don't expect a lot of updates. Check the SVN for progress. Once we are through the middle of October thinks should be a bit better. One thing we are still really looking for is someone willing to help coordinate the Linux port. I think that Dan has done the heavy lifting getting the WX build running, so it should be pretty easy for someone with a linux background. Let me know if you can help.
