Yippee! After a weekend of work, I've finally gotten this new tool for Grease Pencil editing working! Here's a little teaser to wet your appetite for what's coming ;)
The functionality is still very rough - only a single brush is implemented, lots of UI polish is still needed, and the strength of the effect still needs fine tuning. But most importantly, the first version of this tool is now functional! :)
Now, it's time I headed off to bed!
