If you get it installed, it works great!
(I had to do manual file move using SSH (SFTP)) Moving manually files take time. However, it is easy to test extensions and then move them to the production site. I have been looking for such a tool, that does not require deep MYSQL database knowledge.
I hope that developer will add a support forum functionality. An instructions on how to create a manual move/set up, it would benefit the user community.
Conclusion: this tool is worth contributing to.
