Custom CSS

Although this plugin does what it's supposed to I don't want to keep clicking the "buy pro version" button because it is the same color and exactly below the standard WordPress update button in the Publish metabox.  Putting it in that spot with that color is deceptive, if your plugin is good and useful people will upgrade to pro naturally, you don't need to trick anyone into clicking - this isn't SEO!

Pro version promotion over the top

Worthless. Just trys to force you to buy the 100 version

Worthless as a free app

No way to add ANY custom code, but there is a huge "upgrade to premium" button.

Add custom CSS, JS, PHP, tracking code. Very easy to use!
