I just work in the Dropbox folder itself. I.e I do not drag and drop at the end of the day - the code and/or documents live permanently in the Dropbox folder. I truly wished I could selectively eliminate files (don't duplicate .pyc files, or whatever), but it works. A nice benefit is how dropbox keeps backups of everything. A couple of times a stupid moment at the keyboard led me to blowing away a file before checking it in. No problem, Dropbox had it versioned.
