Every time I have a tangential intercept (i.e. an optimal transfer) and I try to put a node on the blue line to tweak my upcoming PE, it snaps to purple instead.
It feels like a really easy change to make the click-detector prefer the earliest time under the cursor vs the latest... in the odd case when someone wanted the latest time, they just need to timewarp a bit
(I know there are workarounds, but I don't moan on here often so this is my rare complaint )
