Yeah agree
I understand OP is continuing the work and improving it as he sees fit, but that in my mind is a fork and should aknowledge the initial work that sparked it.
Maybe i'm wrong tho and this is completely parallel work! Waiting for OPs reply
A fork implies that it builds upon code from another repository. I wouldn't use the word fork to mean "inspired by". I think it takes away from the effort that the author has put in. Anyone can create a fork of a project with the click of a button.
Hi, yeah I'm not basing any of my coding or feature-work on that project. My biggest source of inspiration is actually just a paper poster I have hanging on my wall https://www.axelthorenfeldt.com/news/wwf-verdens-naturfonds-.... I wanted to make a version of that, showing the actual birds in my garden.
