New Feature: New Pixel Pulses
As part of an update that was just pushed you can now enable "New Pixel Pulses" which will make a little circle for a bit surrounding any new pixels that get placed onto the canvas
You can use this to see where activity is happening on the canvas
This was originally made as a userscript by soda_cans and was adapted by me into the actual codebase
I loved this new feature, very cool and useful. It works well for small number of painters and collaboration. :)
