Hey Yinon - have you seen this video - we answer a few points in here: https://youtu.be/xZ6K0_YX4Gs
There are many things that using the phones camera would unlock for Glide. We can’t do it quite yet - as I explain in the video.
For your final question I’m not entirely sure what you mean. If you mean share a link to the current app that is open - yes - you can just add the ‘Share’ action to a button or image.
If you mean you want a link like https://open.spotify.com/browse/featured or https://org.slack.com/archives/2883870d0s9f7 to open Spotify or Slack - then this is also not possible yet. I talk about this in the video above.
