I'd like to introduce the Boomla Visual Designer, or Designer for short. No, that's not an April Fools'. :)
I got plenty of requests for adding various styling capabilities for individual apps. After the basic styling options, like the text color and the background color, it seemed all of you wanted to style something else. The problem with the old approach was that adding any individual styling option would make the most important styling options become needles in a haystack. They also add enormous coding complexity.
Most importantly, there are just infinite styling options, thus no such solution could ever satisfy everyone. We needed a different approach. More like a tool, that you can use to style any of your apps, if those apps support it. Also, adding support for that should be trivial for developers.
That's how the Boomla Visual Designer was born.
