Dropbox has just overhauled its Dropbox Chooser feature to allow developers to implement even more features into their web apps. The new Dropbox Chooser now allows developers to implement the multi-select and built-in uploads features into their APIs. The multi-select feature allows users who use the developer's app to accept multiple files from Dropbox all at once. The built-in uploads option allows users to upload files, either through drag-n-drop or by browsing their folders, directly from their computer to their Dropbox account. Their files will be available immediately through the developer's web apps.
