Feature Request: beautify widgets

[ilka-schulz]

Feature Request or Enhancement

Modern desktop widgets usually have round corners, shadows, transition effects, etc. Is this kind of beautification planned for the project? If no, I would seriously consider using this library in my application and implementing beautification myself.

Additional context

There is no need to bloat the library for microcontrollers with low resources. Beautiful widgets could be turned on or off at compile time.
