I had the following case today: I've set up my app to open every SO overflow from the browser, but I wanted to share a question with a friend to discuss some topic about a programming approach, the issue was that I wasn't enabled to share the question within the app, it would be great if we could have a "share feature" that could pass the url to other application like what's app, mail or any social network.
the workaround was to hold the link in the browser and open it in a different tab and share the link from it.
