yes:
c.TerminalInteractiveShell.space_for_menu=<int>

Likely Yes, but you need to define your custom style:
by grepping through PTK source I can find the following:

Token.Menu.Completions
Token.Menu.Completions.Completion
Token.Menu.Completions.Completion.Current
Token.Menu.Completions.Meta
Token.Menu.Completions.Meta.Current
Token.Menu.Completions.MultiColumnMeta
Token.Menu.Completions.ProgressBar
Token.Menu.Completions.ProgressButton
Token.Toolbar.Completions
Token.Toolbar.Completions.Arrow
Token.Toolbar.Completions.Completion
Token.Toolbar.Completions.Completion.Current

Then you define a Pygments Theme and it should "just work".

We need to write documentation about each of these, if you figure out
all the steps, PR would be welcommed.

good point, do you wish to open an issue ?

I think that using tab to cycle is common, but I might be wrong.

All these never bother me, but you are right.

Do you want to open issue for each of these, we can try to improve
that during beta.

Yes this has been reported, we missed that because of the weird
configuration the developers have.

Thanks for your feedback.
