It didn't work at all. At least not for my store. It completely broke the code. I recommend backing up your code if you want to try it. I wouldn't recommend

Bad app adds a banner to your code and you can't remove it even when you uninstall this stupid app that doesn't even works


Will obfuscate your theme. This is somewhat to be expected, so you MUST backup/download your theme before trying this, and you should really do that before you install any app.

What is not acceptable is leaving the banner on the site. To remove this:

Go to: Layout -> themeX.liquid

Remove this added section of code right near the bottom of this file above tags and save it:
