@Der Pepe (Hubzilla) ⁂ This was my initial try, using MyWiget/MyWidget.php. But it didn't work, so I also tried the flat structure, which doesn't work either.

Using MyWiget/MyWidget.php, the PDL editor doesn't see the widget for a potential install. Or is there any other way to install the widget?

But I'll retry from the start ASAP. Thanks.
