I finally managed to open a system menu....
I just need to understand how to populate it!
First step would be to display in the dropdown menu parents folder and one-shot comics and in the system menu subfolders.
Then I would like to use only the system menu in a way similar to GUI launcher (arrows to view subfolders)....
Don't hold your breath!!!!
PS I *could* even be possible to replace all the alert boxes with a system dialog (==> remove the welcome popup)!
