[UI Feature request] Allow to disable the keywords bar in the interactive prompt

[luziferius]

The white bar that allows selecting/fast typing of language keywords and brackets/other symbols uses way too much screen space and can’t be disabled. Using the stock configuration, it looks like this on my device: My request is adding a configuration option that hides the bar, too.

I was able to hide the action bar in the preferences, yielding two additional display lines.

Hiding the other bar in addition would yield additional two lines. I need those lines to use ptpython as my Python REPL.
