I like the Reverse Route option. However, the reversed track retains the alternate destination, which doesn't make a lot of sense.

If you have an alternate planned, and your current position indicates you're closer to that course-to-alternate than any of your other planned legs, then SkyDemon will indeed assume you're flying your alternate leg. This is by design, and our rationale for not automatically wiping out your alternate when you reverse your route remains the same as described earlier in this thread.
