Hi, Heiko. I saw this feature in LR brushes. It is very interesting. dt masks are indeed more powerful and flexible than LR brushes and with this new feature they will be more and more a real swiss army knife! Hope to see this feature approved and merged in dt git soon.
Thank you for your great work!
