"Lightweight" dialogues similar to current prompts, i.e. not fullscreen

While I really like using this framework to build TUIs I think it lacks the interactive inputs it currently exposes as dialogues as prompt options.
For an idea of what I am talking about see cutie or pyinquirer.

One of the main reasons I see is that many people prefer the look of such lightweight solutions over big dialogues.
Layout is one part, coloring is the other - and I know manual styling exists but is only changes colors and does not preserve terminal styles nor is it able to change the layout.
Furthermore I think such functionality should be included in a prompt_toolkit.

It should also not be to hard as we should already have all the logic to create such prompts from the normal dialogues.

Review the existing dialogue and prompt implementations first, then compare their behavior with the lightweight interactions described in cutie and pyinquirer. The issue needs a defined API and concrete decisions about layout, terminal-style preservation, coloring, and which prompt options are covered before implementation can be considered done.
