Alrighty...
So I'm wanting to 'tentatively' step into custom widget design. I still have a VERY difficult time grasping the Dojo Modules concept, but what I want to do shouldn't require that. So...
I have created a new widget, I called it (ingeniously enough) "MagnifyingGlass" because that's what the end users want.
- I have copied from the WAB Sample Widget the SimpleWidget folder structure for the 'Get Map Id' widget example.
- I have renamed everything.
- I have added it to the site config file so that it shows up.
- It is now visible on one of my dev maps.
- It is the button that is a Duplicate of the BOOKMARK widget button, in the bottom left set of 4 buttons.
