In addition to developing his own Windows apps, Rudy Huyn also works on official apps for others. That includes the official Dropbox apps, and the Windows 8.1 version just got updated in the Windows Store that adds better UI support for smaller tablets.
Here's what's new in version 3.6.1:
- Improve UI for small tablets
- Add labels to application bars
Huyn also announced that the new Dropbox version makes "text selection possible in the text file viewer". Huyn recently updated the UI of the app to make it look more like a Windows 10 app, even though it's still officially a Windows 8.1 app.
