I realize this is a trivial ask, but if you ever have spare time, NM traveled would be a helpful addition to the flight plan grid.

I have to turn the flight plan table from a static one into a more dynamic one which changes during flight. Not difficult but it has to be done. 🙂

I added this to the flight-plan-table-new-columns issue: https://github.com/albar965/littlenavmap/issues/371

In my spreadsheet it was just a simple formula, so the column can be populated from existing data before anybody even takes off. All I would do with that value is get an estimate of how far we've gone and using my aircraft's cruise speed, get an estimate ( in my head) of whether we're likely to finish the group flight in the two hours allotted.   So I suppose an alternative would be time remaining until destination ( with current aircraft performance)  -- which again can be populated before any travel has taken place.

At this moment, for this purpose you can use "Remaining" column in flight plan. It shows a sum value in reverse order (going down from whole distance at departure to 0NM at destination) which shows you how far is your aircraft to the destination  🙂

Let's say the remaining nm column shows 237 NM and you have a ground speed of 126 knots.  You can guess just under 2 hours to reach final airport.  Of course many of these flights have climbs over mountain passes.  I suppose Alex's comment about a dynamic set of values would actually be best because with a connection to the simulator, LNM knows where you are and how fast you've been traveling.   Such a dynamic estimate would be based on either your current speed or average speed recently. If you all of a sudden drop your average speed due to many mountain passes, then ???

If we say about dynamic calculations, IMHO better is dynamic estimation of remaining distance instead calculation of flown distance - at every moment you  can see how far from destination you are  and this is constantly  upgraded  based on values from simulator. 
BTW from math point of view both sums are similar only in reverse order, but for me it's easier to read how far I'm from target, not from departure.
As you noticed the average enroute ground speed can vary, so it means the average fuel burning also can varies dynamically and when I directly see what is the distance remaining to the destination and how much fuel remains at tanks, then I can quickly decide whether it's necessary divert to alternate or not, without any special/additional calculations  😛

Hmm ... if it is just about the two hours: You already get an estimate of flight time to the destination and ETA in the progress tab calculated based on performance file (legs ahead) and flown speed, etc. (legs passed).
