PLIST Editor allows you to create, visualize, modify and save property list (.plist) documents. PLIST Editor is probably the only "source control friendly" property list editor that you can find on the market (except Xcode, of course). For all plist types (XML, Binary and OpenStep/ASCII), it maintains the order of dictionary elements and the editing capabilities are on parity with Xcode, so you don't see a difference between a file edited in PLIST Editor and one edited in Xcode.

Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
