Just a brief note on the topic from discussions and testing that we’ve done. Having some ground item labels being different heights is a non-starter. Unless something dramatic changes, we have no intention of making the height variable from item to item. Similarly, having the clickable area being larger than the visual area is also not going to happen.
Both of these things cause major problems when larger quantities of items are on the ground and without something revolutionary (that I can’t even fathom what it could look like) we aren’t going to add those options.
Having a setting that scales all ground item labels uniformly is possible but we don’t have any plans to implement that feature yet.
