A plan you import now stays on until you change it. Addon version 0.4.77 carries that and two fixes to your route.
Imported plans stay loaded
An older plan or an automatic replan no longer replaces the plan you import. The tracker shows when an imported plan is on.
Flights in a row are one step
Change planes without landing for a quest and your route counts the whole trip once, from your first flight master to where you touch down.
Turn-ins that wait for your route
A quest that is ready to hand in no longer jumps ahead of your route when your route doesn’t include it.
