A tough one. I can see your points on both. I think I like the second one a little better, perhaps with a note about swiping to continue or for additional info.
I agree it’s a tough one. At first I liked the first version, having all the actions to choose from. Then my thinking was what would I do most often? In other apps it is mostly hide and show, renaming, deleting not so much.
Therefore I would go with the second one and keep the clean look, something I think Shapr does so well. A tutorial, the bumping, and like other actions, use would take care of the discoverability issue. I think the need to swipe would become intuitive after a few uses.
Both options are good. However my vote is for version 2 with video as was suggested and clear symbol that indicates more >> many users are already used to swiping in procreate and other apps. It will become second nature very shortly.
Will there be a group? layer color change also?
