Arrows are not easy to identify or get too long
Sometimes I have VERY long arrows. When i highlight the arrow I can see it nicely, but as soon as I try to move it is not highlighted. I want to be able to see my separate arrows ESPECIALLY WHEN THEY overlap.
A few options to consider.
Allow me to color arrows different colors for visibility.
Allow me to select an arrow and leave it “selected” so it stands out.
Allow me to have a shorter arrow that goes to a “GO TO” element which is just a pointer to another element in the flow.

I often use Decision steps to gather multiple arrows together, just to make them easier to manage. It's not a perfect or dedicated solition, but it's similar to your third option.
