Hi,
A minor point, but I would love to be able to visually see which end of a wall is the start.
This could be a different colour or shape of the grip when click on the wall - say the start has a green grip as opposed to blue.
The problem I have is when I want to change the endcap of a particular wall, I don't know which is the start or end and so I have to guess (which is usually the wrong one).
