I did a two-day project to rewrite our web-based prefs system to run in Bootstrap tabs.
It works great. Then I went one step further, and created a new worldoutline nodetype called tabs. So you can create a tab-based interface without knowing any HTML.
It's pretty amazingly easy.
Here's a demo.
And a screen shot of the editing environment that created that document.
Have to keep working on connecting up all the bits so this software can be used by lots more people.
