Since we last featured the Dropbox UWP app, back in May, the developer has been beavering away and the result is another big update, v4.4, with the changelog quoted below. Almost all the improvements are common to both PC and mobile/phone, thankfully.
Here's the quoted Dropbox UWP changelog:
Open the app to the last visited tab
Print your documents stored on Dropbox! Supports PDF, Word, PowerPoint, image and text files
Share an individual file with only specific people
Create and manage password protected shared links
Text previews now support syntax highlighting
Redesign of the file viewer for phones to optimize for more space
Performance optimizations
Quite the update then - and a must-have for anyone whose smartphone is now on Windows 10 Mobile.
Of the various navigation tabs - the one you're on gets opened first next time around...
Printing is available, much as with Office Mobile documents, but you'll need a compatible wireless printer - my Canon 2015 model is not on the list (sob)...
The file viewer is very well thought out, the range of stuff that can be previewed in the app is quite impressive. Long documents have a thumbnail overview too....
Setting permissions on a link (no idea why it was greyed out for me - more investigation needed!); automatic colour-typing of source code and other markup languages...
