I was trying to make some “natural” RNA puzzles, and I’ve noticed that often times, the branches of a multiloop overlap ingame. A more diverse selection of puzzles could be made and solved if you could:
- change the angle of the bend introduced by internal loops.
- “slide” branches around multiloops.
You can do this in VARNA by clicking a stack and dragging it. I’m not sure this would be very easy to do in EteRNA, though, and I’d understand if dev time could better be spent elsewhere.
