I am a big fan of easystroke on Linux (Ubuntu). But unfortunately it's not updated.
From time to time I encounter some issues with easystroke. For that reason I kept looking for alternatives. But found nothing satisfy me.

When I noticed mouse-actions developer is also easystroke user, I felt excited and wanted to try it.

The GUI starts normally but, I couldn't manage to enter "Command" in the text box. It looks like read-only. I can enter comment but not the command.

I tried it on Ubuntu 20.04 and also on Arch Linux. Both have the same problem.

What should I do?
