(this is basically just a simplified version of this)
I have created a simple userscript that shows a small tab above every code block that tells you its character count. I posted it on Stack Apps, but I thought I would also post it here so people from codegolf.SE will see it.

Example:
window.onload
. And it would be nice for userscript novices such as myself to see a comment explaining why you go through the rigmarole of injecting a string to beeval
ed. \$\endgroup\$$(this).text()
. I'll add an explanation once I have access to a computer \$\endgroup\$
