Adding more actions to a widget

[webord]

On the Widget UI, there is a "Close" button, aside with the "Delete" button, and I that developers should have a way to add more of those.

For exemple, I would see as a good use case when you have a way of previewing the widget.

Because right now the only way is by JS which is kinda of lame.

Thanks,

But wouldn't you need a JS handler for the "Preview" button anyway?

[webord]

Yes, but why adding the handler with JS if you can have the server generate the HTML for you in this case. Might be a good addition to the Widgets API having these actions built in.

But I see your point.
