I recently published a plugin that transforms your app’s font sizes to flexible sizes.
FitText transforms the size of your app’s fonts into flexible sizes. Use the plugin in your app to get scalable title results that fill the full width of your element. The “FitText” plugin will only work on the “Text” element of the Bubble.
Take a look at our demo page for a showcase:
