My English is not very well,thank you for taking your time!


It's not possible to edit the view's title or the default category titles. They are all hard coded.

if I modify the code of the KNIME,whether I can  edit the view's title and the default category titles.

And I have been successful to modify the name of the node like the picture.

The categories are defined in several plugin.xml files. The view's title probably too.
