Here’s another killer feature for Dropbox. They have this Selective Sync thing, which is cool if you don’t want to burn your entire dropbox storage with files that you don’t need to backup. But the reverse is probably more important because local storage is more precious than Dropbox storage. So they need to add the ability to set files to be “archived” meaning they live ONLY on Dropbox and not on my local drive, just an alias is there that prompts me to download if I click on it. Saves me mad space for files I don’t really need locally. Yup. Tight.
