Created The Fill Lasso Tool

It's really good for blocking areas, creating silhouettes, etc.

It's the lasso tool but also fills, so you can make super quick shapes. I've been using it to do shading work and it's hyper quick and fun to use. I hate creating shapes and then filling them with the bucket tool, it always leaves a pixel unpainted.

Really cool for sketching

I've been using it a bit for sketching. It's surprisingly friendly for drawing lines, but the shape part is the best.

Opacity

You can also use it changing the opacity, meaning you can quickly create gradients without blur or soft transitions.

So, if you want to use it, just head on to, it's free:

Have fun with it!
