Good and useable feature, but let's be honest, we all want a VFB+ rip-off with more refined interface and corona oriented controls like already implemented exposure and hopefully next coming vfb dumping/resumal/etc. or at least I really do :) Jokes aside some features found in VFB+ are really game changing and it would be really awesome if some analogues of them would be implemented in corona's one and of course, region render in corona's vfb is a must, it is really cumbersome to use both default and corona's vfb's at the same time just to have that function. But nevertheless that's a great addition as always :)
