Description of the feature
The antline transfer system from older versions of BEE still works in modern BEE, but the current implementation is broken. (#3051) It can be re-enabled just by swapping out a function block in each geometry block config file.
Why should this be implemented
I understand that reconstructing the antline transfer system to be better than before (less stretched antlines, etc) is on the to-do list, and while I look forward to it I think that the ability to move antlines on top of geometry blocks is so extraordinarily useful in layout design that re-implementing the old functionality in the interim would be worthwhile, even if some of the antlines are oddly stretched.
Additional information
I have done this with my own geometry blocks.
