More information about customizations
First of all, congratulations for a really good work so far. Those widgets are really a must use, there are many others but the usability and the minimal changes required to adapt existing code really makes them shine above the competition.
And then, right now it lacks a more in-depth documentation regarding the styling that can be used to change several aspects of the widgets.
For example, the display of contents of the bubble widget introduced in the latest build (0.5) can be controlled with the 'm-bubble-content' class. Even if it's pretty simple to find, it's not documented anywhere.
Also, the main bubble class is 'm-bubble', I needed to change the z-index as it was partly drawn below another control.
Anyway, keep the good work going!
