Highlight visited & watched threads Userscript

[Troopy]

I wanted to share this userscript I found on Greasyfork that highlights visited links across (AH/DLP/QQ/SB/SV). There are more features on its description page, but I've found this basic highlight invaluable over the last month. I can tell at a glance what links I already opened and watched, it's made discovering new things easier instead of re-reading the same threads over and over.

I'm using it on Firefox mobile with the violentmonkey addon like it says, but any script manager such as tampermonkey should be fine.
It has so few installs, I hope that someone else will find it useful as well.
