I wanted to create some number stats for my blog, but I needed to count a lot of different things manually because the number stat was based on the content of art posts. My brain memory for counting multiple things is limited, so I created a small quick counter app/script for Greasemonkey and Tampermonkey.
Now I can count specific content on my art blog with counter buttons.
Click add counter to create a number input. Counters are unlimited.
Click +/- to add or subtract to that input.
Disable the script when you are not using it. (it has a * global include)
