Anthony, this is what I have found out.
I can confirm there is a variation in placement of new layout (from V19). This is when using the right-click and copy method.
However, when I copy through the "layout manager" (see button to the left of the tabs), the new layout is still placed at the end as before.
Not sure about prioritizing, but I've gotten in the habit of only keeping Endpoint and sometimes Midpoint active as snaps. Any others I need, I type the three letter shortcut for. There's also Shift+Right Click to bring up the snaps context menu.
