Quality icons seem to stay on even if ALT mode is off. not sure if its intended

Howdy! This is a reasonable request, and I believe I can make it work, so I'll push out an update in due time.
One thing I was considering was perhaps tinting trees certain colours depending quality, but that is more technically challenging at this stage.

I'll admit this request had slipped my attention, however thankfully another user has helped implement a fix and the latest update ties sprite to altmode! Definitely a more appropriate behaviour.
