Feature: Display list of files as preview for folders [Discussion]

### What feature or improvement do you think would benefit Files?

Instead of nearly useless icon the app can display list of files and subfolders on folder preview. Even simple list is enough, but also nothing stops from displaying full interactive folder view, clicking on which affects main window navigation. That turns the app functionality near the miller columns which I find the good and useful addition. No need to display full folder tree — that will make a mess and slow down the navigation.
