Right now there are no bulk actions available in one’s widget list. So if you wanted to delete a bunch of them at the same time you can’t. Would it be possible to add bulk actions? Would be really useful when you want to make mass edits across your widgets.
Overall I like the way the plugin is designed, congrats!
But that’s the thing, I don’t want to delete them one by one, but would like to do it in bulk. You have already implemented what I’m talking about in your other plugin (Announcer), here’s a screenshot of what I mean from Announcer.
