Hello again, when you have used Sioyek much later, to open many tutorial.pdf files of other things, you will not know where the Sioyet tutorial pdf is. The name to is to generic, so call it sioyek_tutorial.pdf in future releases, it’s more specific. This is when you use many times the Shift + O to open the las opened files.

The very best regards, João
