Whether making fine changes to existing, purchased, or your own custom templates, you need this tool. The number of steps it takes to make CSS changes in the core setup is a bit insane. This tool is a time saver, making the whole process pleasant and instant.

Once you are done modifying a site, you can hide the tool to keep clients from accidentally making changes.

I had a minor issue, and the support from mesuva was quick and excellent. Don't hesitate to get this add-on; if you have or plan to have multiple concrete projects buy the 5-pack (totally worth it).
