@Simeon - firstly a thank you for the modified archiving option. After a gap away from Codea came back and used the archive option - much better, faster and more compact. I moved the zip to Dropbox, noted the sync has disappeared from Documents. I unzipped the file and found that the projects appeared to be arranged in collections - is that the case?
If so is there any way I can take a collection and re-zip it so that I can load and work on collections (I have loadsa project files in my iPad)?
One gripe, the text at the bottom of the archive window is unreadable on my iPad, just see the top of the sentence. Need a bigger window.
