Selected Tab custom text color

[Skirtek]

It is impossible to add or change text color of selected tab when using your plugin. This feature is easy to achieve native and in custom renderer by adding a few lines of code. But if we want to use your plugin this feature is impossible to achieve. Could you try to add this?
