I am NOT a programmer, but as a Creative Director, I'm often looking at websites created by either my team or contractors. One of the difficult things to convey in providing feedback is where I need more padding, a color change, etc.

This tool REALLY helps. I can provide a video screencast where I can talk through the changes I want, and then make a quick CSS edit using InTab, download the file, then send both the video and the code off to the developer to mess around with.

Honestly, I can see this being a great tool to learn CSS just be debugging other websites. While I absolutely want the founder to grow this product, it would be nice to have an onboarding process that guides users through the different portions of the extension, especially for the layers. A simple 3-5 page setup with each page having some element that can be changed with a prompt that says, "Open up InTab and add 50 px padding to the logo." Short exercises like that could really go a long way for onboarding.

Other than that, I'm really quite impressed and excited to use it on my next web project with my team. Great job!
