New and revamped UI in PicsPro for Picasa 4.x

As some of my users have repeatedly mentioned, the UI design of PicsPro looked quite dated - that is, until now.
Starting December 16, a fully revamped version of PicsPro has been published on Google Play.

Here's what's new in PicsPro for Picasa 4.x:

• Sliding drawer menu
• Interactions comply now with Google's Android guidelines (the old version of the app had HTC-style thumbnail selection - the ones where you had to select the feature first, then select the thumbnails)
• Better caching
• "Select all" in every thumbnail view
• Compatibility with high-resolution phones (1920x1024), like Nexus 5
