Dropbox adds PDF Viewer and in document search

There is an update coming to Android Dropbox users. It includes a built-in PDF viewer and an in-document search feature. If you view a lot of PDFs on your phone or tablet, Dropbox now allows you to share the file straight from the viewer, which will automatically save it in a Sent folder. This will make sure you don’t lose track of those important documents. 
The in-document search will allow you to find specific keywords within any document. This can seriously reduce the time it takes to find the section of text you are looking for in a document.
