In flowchart material, a sticker is some functional 'adhesive' metadata* that can be added to a cell, post or post object, creating texture - usually to enhance said cell, post or post object without (further) verbalization.** A motion or still/static picture illustration in most cases. (see hologram, stamp, postcard, patch, hyperlink, carrots🥕+peach🍑)
/// I tend to use stickers as a way to receive tips💰/bids (eg. time-sensitive tags) from clients. In the wider context of juking, players may use stickers as game beacons.
