The Evernote client has continued to add new features since it was first released, and this has continued since the third major release earlier this year, and it is good to see this pace has continued. Yes the changes are small, but they add to a much better experience and they don't diminish the functionality already there.
From the directory listing's change-log:
New in v3.1
- New Snippet View displays notes in a horizontal list.
- Pin tool tiles to your phone's homescreen.
- Numerous bug fixes and improvements.
You can download the updated client right now from the Windows Phone Store.
