Generally a good addon BUT in its current state unuseable. The automatically generated watermark is taking a comically big chunk of the video, asking you to buy a license.
I am not against monetizing your work if it is a good product and the price is right.
Yet 18,50€ is just absurd.
Additionally I am a bit confused about some of the recent reviews around here, giving 5 stars using the exact same wording. Is this an attempt to counter the 1 star reviews after monetization?
I am strongly advising the dev(s) to rethink their current approach
