I’ve added the following new features to Keep Calm 2.31:

• A ton of bug fixes, the app is a lot more solid now
• Pro users can now crop, scale and rotate their custom icons (this feature will probably be added to the background import at some point soon too)
• Purchasing upgrades is now a lot faster. Technical explanation: Previously when you pressed to purchase an upgrade it made a request for the information about the product from Apple, meaning there was a delay of a few seconds whilst this information was received and processed. Now as soon as you enter the store the information is fetched, so payment now has one less step, making the whole thing a lot faster :)
