If we buy theme editor, what will be the benefits of it?
Please tell me the benefits of it.

You are able to edit your theme directly from browser, so you don't need to have a connection with FTP. It can be a huge benefit if you are a developer and your customers are submitting many small tasks, which are not hard to solve, but a time consuming to connect with their store each time and modify files. With Theme Editor you can just login and change necessary files. The process, which took several minutes, takes a few seconds.

That was the main reason for creating this plugin. In our case it shorten the small issues resolving time.

Best,
Patryk
