Please elaborate?
Also note that whatever feature it is, it will have to wait until the rewrite is complete (which itself is delayed until I fix oxr)

On converted maps hold tiles has no reverse arrow

I'm not sure that would be very readable, and this ruleset already has problems with readability as is. Although, perhaps this could be converted into spin tiles if there are enough repeats?

[IllianDeCube09]

Maybe, make conversion depending on the speed of the repeats. For example, at low speed, just reverse movement, and at high speed, something like score points on the way, so as not to lose readability.
