Not a bad idea. How it works currently - I believe is that the source is not uploaded when publish is unchecked (just the compiled java bytecode and resources). Would be no difference other than visibility among users (compared to having published the source), to have a "private" option. I've always just used a flash drive or email for carrying my versions around. It seems just under half the scenarios on the site have published source code. (number of pages under tag "with-source" compared to number of pages under latest scenarios). So all those without published source code saves decent amount of space. Guess you could have options for source: 1. Publish 2. Upload (private) 3. Exclude

The problem is, you don't select to publish the source code, then the source code isn't uploaded. There's no way you or anyone else could download it. The gallery is intended as a way to share your work with others, not as a temporary storage for work that you're currently doing. The best solution for carrying work between two locations is probably a memory stick, or use dropbox or a similar tool. Or, upload it to the gallery and make sure you check 'publish source' - that's not really very hard.

davmac has a good point, dropbox might be more what you're looking for if you want to access your source in class. On top of that, clicking publish source has no drawbacks really.
