@etiennebacher We have improved the display() method throughout easystats, supporting tinytable now. This PR updates (or adds, if required) the display() methods to support format = "tt". Furthermore, the methods also appear in the docs.

Thanks, just a few comments to address and then this can be merged.

Also there's some styling to fix apparently
