TabUI collapsing/expanding improvements

[guaje]

Is your feature request related to a problem? Please describe.

As shown in the following image, the TabUI starts in collapsed mode.

Describe the solution you'd like

• It would be helpful and more intuitive if the default behavior of this UI component would be the opposite yet still provide a parameter to initialize it collapsed for some applications.
• Additionally, it would be great to have the option to collapse/expand by double-clicking on any tab or single clicking on the active tab.

Hey, I would love to work on this, could you guide me through it?

Thanks in advance.

Sure, create a PR in which you add a param to initialize the TabUI in expanded mode (init_expanded=True), implement the corresponding behavior, and of course, implement the opposite behavior. Then go to the related test file and add a test case that test your new functionality.
