I hope, i can explain with words. 😃 On mobile devices, post URL copying so hard imo. I prefer when i touch to post url for copying, progress done automatically for me to clipboard. Or need "Copy" button like a YouTube videos share experience. If isn't clear, i will explain with pics.
Talking about this area:
For desktop, CTRL+C is so simply but for mobile devices hold your finger on URL and press copy to clipboard. This is so much step for casual users.
