Like it or not, “the cloud” has become an essential part of modern life. At the very least, more and more people are using cloud storage to hold their files, especially the ones they need on the go or to collaborate with others. Cloud storage, however, really offers just that: storage. To do anything with the files stored in them, you often have to not only launch other apps, you also have to download and re-upload them in the process. That’s why Dropbox has developed a new Extensions system so you can do all of the things you need to do without leaving Dropbox at all.
