Thank you for your kinds words. Batch rendering is definitely something I wan to add, hopefully next in the release it will be included.
This addon is life. The only nitpick I have is that I didn't find an option to list he duplicate images & meshes before merging them, but aside that, it's a lifesaver tool for people who like to keep their .blend tidy
Used it for preview renders so far, really neat and handy, more people should use and know about this addon. The "Render Normal" button also fixed just recently, which I really appreciate.
The only thing this addon needs I think is a batch render option; for example, if I select multiple cameras and hit "Render Viewport", then all the selected cameras would do a viewport render with their custom settings. Additionally a "render all cameras" or something like that.
But the addon is a lifechanger as it is.
