Hello Enug,
Thank you for responding immediately. Tomorrow I will make screenshots from the menue and what appears after I clicked on ' Werkzeugkiste". And I'll cite the paragraph in which was explained how we can implement brushes and almost only from Photoshop. Maybe I find the thread here where is shown by screenshots how it works. Which made me recognize my Werkzeugkoffer/toolbox does not work/exist.
Have a nice day and don't worry, it is all not urgent.
Regards, W
