Currently when you share a photo from Glass, that action leaves a card in your timeline. (For example, sharing a pic to G+ results in a second timeline card of that picture with a little G+ icon in the lower-right corner)
If you share immediately after taking a picture, you end up with two copies of that picture next to each other, which quickly becomes cumbersome.
Ideally, a SHARE action (or a contact registered to receive those actions) would include a flag such as "persist card" or "don't show SHARE card".
Other than immediately deleting the timeline id responsible for the share (which isn't very synchronous), does anyone have any idea how to share many photos without cluttering up the timeline?
