Processing Sketch Browser

A sketch browser would be really handy, especially once you start collecting a lot of examples over the years. Even simple features like tags, search, or preview thumbnails would make finding old projects so much easier.

Yes, it has preview thumbnails. It runs each sketch for 5 seconds and then shows that tile as sketch and you can click any of them.

I agree with you 100%

Click a tile and CTRL+DRAG to flip it with another tile and let go. A line will connect the two before they flip locations. You can also drag and drop your own .js sketches onto the tiles. Make sure they are 255 x 255 ideally
