Got all gestures wired up in Identity: there's drag-and-drop heavily inspired by Loupe with its beautiful thumbnail (naturally, in Identity it shows playing videos!), there's drag to pan when zoomed in, there's click to "select" a video tile.
I love how easy it is to do drag-and-drop while showing whatever in the thumbnail in #GTK 4 (especially now that sizing and hotspots work ;)). Thanks @sophie and @brainblasted for things I stole from Loupe and @alexm for help with gestures!
