Some extremely useful enhancements for briefcase. Let me know if current version can already do these:
1. Enable to upload a folder filled with files instead of having to select files to upload one by one. This will save time and improve productivity.
2. Dropbox feature whereby user can add or upload files, but not edit or delete files. This will be extremely useful for collaboration whereby everyone can share files without worrying that their files get deleted by other users accidently.
