I use a Catch —› Collection app called mymind. It’s perfect for catching, tagging and storing clippings, URLs, images and stuff from your mobile device (I find it far more useful than bookmarking). It looks like a Pinterest board that you can add notes to the capture and create custom spaces. I’ve sent the folks from mymind.com a couple of nudges via Twitter and their contact form. Here’s their link: https://mymind.com/ Love to hear your thoughts 
On an infinite timescale anything is possible, but I’d make a hefty bet this won’t get added into the core Obsidian.
