Post count can be done with custom javascript.
Open the developer tools, drop it in the console.

DO NOT RUN UNTRUSTED JAVASCRIPT, VERIFY IT FIRST

Hacked up example below; not by any means ideal but works:

var nav = document.querySelector('nav')

var span1 = document.createElement('span')
span1.innerText = '[ postCount: ';
