Update Wishes to get a better Google Page Speed Result?

Hi There,

is it possible to use the font-display CSS function so that the text is visible to users while web fonts are being loaded?

or maybe Webp converting?

or Resources block your page’s first paint. Try to specify important JS and important CSS inline and postpone all non-critical JS and styles?

Is there any thought to get one or more of these in the future, to fix some of the issues of the google Page Speed Results?

Thanks in advance KiM :)
