Hello,
I am a linux and long time Krita user and just came across this plugin. However, after following the instructions for the latest version I get an error after enabling it.

`AttributeError

A problem occurred in a Python script. Here is the sequence of
function calls leading up to the error, in the order they occurred.

The above is a description of an error in a Python program. Here is
the original traceback:

I hope that this can get fixed.
Thanks for sharing this plugin.

Just go to the line 25 and erase a coupe of lines, if you read in the file comments it will tell you that it hides some buttons. QWidgetItem doesn't have the attribute itemAtPosition and for a little research I did it seems QWidgetItem is from Qt.io a framework. After you comment(put the symbol # before the line) and save the file it will launch.
