Just installed the updated app to my phone. Noticed a few changes.
First, they've added some text formatting. Bold and italics. Which could be handy.
Also, they've added the ability to insert a link. So that its clickable.
And you can now resize the photos you add to your posts.
And probably the most important is the ability to edit any post. Even ones made from a computer. So its fully synced now! Yay!
