Dropbox has updated its Android application to add some essential features to the app. The search feature now lets you look for documents placed in folders and the app will suggest results as you type them. The cloud storage app also remembers your recent searches and highlights the names of files that match your query. The document preview feature now also shows you what is stored in a specific file. This is particularly useful for those who save documents using specific or weird filenames. The update is rolling out and will probably hit the Play Store real soon.
