The minimap helps the user to find where his code is located in the file. A minimap in the tabs could help the user find what file he wants to edit easier.
Looking at an image is always easier to identify than looking at a filename.
Wow, I don't know what happend but some of the text is gone..
Basically, I was speaking about adding a preview in the tabs. Something like the minimap that ST already offers, but in the tab. I'm not talking about some HTML preview.

As you can see on the transmit and transmitEffects we can see a minimap of the code. It helps switching over files on larger projects.
