When you make a website into an application shortcut you don't get the toolbar in the top, where the chromecast button (from the Chromecast extension) is located. Therefore, you cannot cast a Application Shortcut tab. This is true even if you add the --enable-extension flag to the application shortcut flag.
Is there any workarounds that will let me chromecast such a tab?
I'm thinking something like an extension that enables you to set the chromecast command to a keyboard shortcut, or one that adds the chromecast command to the right click menu, but I haven't found anything like that yet. If not, could I make such an extension myself or is it not possible to call other extensions like that?
