Thank you for pointing out that one item. I saw others but I did not know what your problem is.
Vague criticism is not helpful. People have worked very hard on projects and are limited by time and resources. There are many things to work on to improve a toolkit. Just saying something is “very bad” does not give any information on how to improve i lt. It is just a negative comment. I can not create an issue based on your initial feedback that could be worked on.
If you have specific feedback I please create a issue in the SimpleITK github issue tracker: Issues · SimpleITK/SimpleITK · GitHub
Thank you for your engagement and input to the ITK community.
