How to change font size

[skyride99]

Can you expose a property to expose fontsize so that it can be styled?

You can use the custom view option to render any font in any size as you like, see CustomViewTabLayout.js

then the icon and text can not be centered.
The icon and text dont respond to align.

I am having the same issue, I have an icon and a text element inside a tab. They do not get centered properly :(
