Mac: Droplings is a free menubar app for the Mac that makes it easier to share files with friends and colleagues through Dropbox. Just drop a file on the menubar icon, and the app builds a preview page for the file, uploads the file and the preview page to your Dropbox account, and then copies the URL for the relevant URL straight to your clipboard.
Droplings' developer built the app because he uses Dropbox to share files with potential clients and coworkers, and likes having a professional-looking preview page for each file he shares. He has made the app free while it's in beta (the final version won't be free). Despite the beta status, it worked like a charm in our tests.
Dropbox is great for file storage, and we've shown you how to use Dropbox to make working in groups easier. The ability to share a link to anything in your Dropbox means it's easier than ever to never send an email attachment again. Droplings piggybacks on that functionality and makes it even better. Give the app a try and let us know what you think in the comments.
