@Grace, the issue is that there are now two independent forks of the project that are diverging. Roman is continuing to develop his own fork under the name Valentina, so if we also stick with that name, it would create a lot of confusion. Right now, the two forks are nearly identical, but the differences will only grow as time goes on.
I’m new around here, so I don’t expect my opinion to count for much, but I think leaving the Valentina name with Roman is the right thing to do. I know nothing of fashion, though, so I won’t even try to propose a new name!
