Awesome stuff.
It requires some polishing though, but I prefer it over many apps.
To me - it didn't work well with USB camera on a laptop - it could only choose one and it was the one built into my laptop.
Take the feedback, do some improvements. I will use it even if you don't - love it :-)
Thank you! If you're willing to provide feedback over time, I'll implement features you're looking for if you have legit use cases for this tool and are willing to use it. I'll give you free service in exchange once I begin charging.
The aspect ratio issue you mention has not been well tested, and your feedback is already very valuable. I will fix this.
