Just a small suggestion, but I’m surprised that when rendering using an already existing filename, there’s no option to increment the filename by appending a (1), (2), (3), etc. Right now my only option is to overwrite the file or cancel.
This would be useful for comparing old and new renders without having to manually rename anything. My current workaround is to add a current time+date tag. Numbering the files would just be a bit cleaner.
