[Feat]: More controls need Tab Index

[ScottKemp]

Is your feature request related to a problem? Please describe.
When trying to quickly enter data into a form as an end user, I click tab to move from one field to another. The tab order is all over the place. I kind of expected it to just work as is, top to bottom.

I did see the Tab Index in the Edit Input control, and that does work. But then there is no Tab Index property for the Select Control or Button, for example. I suspect many other controls are also missing it. Without this or some kind of predictable auto tab order, tabbing is essentially broken.

Describe the solution you'd like
Either get an auto tab solution to work, Or Add Tab Index to all controls.

Describe alternatives you've considered
No alternatives
