I think that Bootstrap studio is great. I would use it as my main development tool but for a couple of issues. These issues have been mentioned time and time again.
1. To be able to export files with a user defined file extensions. such as, .PHP and .ASP.
2. To be able to publish to a user defined server.
I have purchased a life time licence to help the product survive but without incorporating the above I may have to cut my loses and stich with other tools that meet real needs
