Sorry for that, it was not my intention! I didn't think about this! I wanted a better GUI and a simply to use app only!
I see two possibilities:
1. I write your name in the about dialog and the code
2. I stop the project and delete it
What do you want?
I'm usually glad when my projects are being used, improved and derivated by someone. Actually I encourage such actions. But it's not cool when someone just renames them and make it look like it's an original work. Anyway, this is what I would expect a derivator to do:
1) Include the name of the author and a link to the original project website (see my previous post) in the "about" box, README file (if any) and in the website(s) of the derivative project (e.g. this thread's first post).
2) Make every necessary effort to avoid the impression that this is an original and underivated work.
3) Make all the source code available right away, commenting your changes to the original work whenever possible and keeping the credit to the original project and author in the source files.
There's much more on the GPL model if you're willing to read the whole thing, but these are really my only demands.
I'd be pleased to see my work being improved, disseminated and actually being useful for free, and also I'd be available if you need any assistance with the original code.
