Rated 5 out of 5 stars

Sorry, but 'customizable context menu options' never works for me. Without that feature, the plugin is totally useless.

Hi, Juraj: It's very likely that I did something wrong. I have reinstalled the extension and it works perfectly now. New rating: 5 stars. It's very useful. Thanks for answering!

This review is for a previous version of the add-on (3.5). 

Hello Klaus,
Could you describe what exactly you did?
The context menu options are editable from the Settings / "Context menu options".
I've tested it now and I can add or remove existing and they are correctly updated when you right click.
NOTE however, that items without "%s" will be shown only when you right click without selected text. I should probably write it there.
Best Regards,
Juraj Mäsiar
