I think that's outside the scope of Plash.

You can kinda solve this with iframe/frameset as long as the website you want doesn't prevent being embedded in an iframe. There are of course ways around this by using a proxy server that strips the Content-Security-Policy header.

I do want to make a different app where you can open multiple web browser windows as widgets on the desktop, but it's not something I will be able to work on anytime soon.
