I'd like to create both modal and modeless dialogs.

The popup.html would almost suffice as a modal dialog, if it weren't connected to the frame like a "speech balloon". I'd like to be able to drag it around the screen.

And a modeless dialog, always above the webpage, but allowing mousemove and click events behind it - is that possible? Maybe with a new chrome window, but without url bar, menus, etc?


Modifying the website is not an option - I can't modify the webpage's DOM, and it might have Frames I wouldn't want to deal with.


I've done both of these with IE and Firefox; just wondering if Chrome can too.

Not with Browser/Page Action pop-ups.
I'd suggest adding a window to the DOM with JQuery (since it has insidey window functions). But since you don't want that I'd say there might be something in NPAPI you could do..
