I think I never actually made a topic for Sculpt Tools here despite having written it a year ago. So I'm making one now since I just updated it with some new goodies.
So what is it?
It's a little bunch of operators that make some boolean and modifier-based actions easier and faster to work with.
So what's new?
Cutting meshes with Grease Pencil thanks to Iceking
Updated and de-crufted for 2.69
Where can I get it?
Or here's a direct link to the zip.
What does it look like now?
Where can I find it?
In the toolbar.
Also, there's a handy Ctrl-Shift-B (B for Booleans) context menu.
Feedback naturally welcome.
