You are definitely missing out on Scotland, Portugal, Scandinavia.
Even more so Poland and the Baltics.
Oh, and too little of Italy 
What’s with the South West of England? Does it have a contagious disease or do you have “there be dragons” printed on your charts??? ;-)
VFR trips (perhaps 50% of my flying time) are missing. Intra-UK stuff I do VFR, or “ad-hoc” IFR. See the two links in my original post. I have done loads of SW UK e.g. Henstridge, C/Abbas, Exeter, Plymouth, Bodmin, Eaglescott, Scillies, Perranporth, Newquay, Bristol, Cardiff, even Heywood Farm with its 8" grass
VFR trips are in Navbox but you can’t load more than one route into that at a time.
Also the 2014 Bergerac-Lucca flight is not shown.
I planned Crete-Constanta-Odessa-Slovakia a while ago but now there is no avgas down by the Black Sea.
I planned Poland a while ago too but the people I was going to see saw their business (an aviation mag I used to contribute to) go bust.
Italy, I have done Lucca, Elba, Padova, Trieste, Caglieri, Albenga, probably some others. There isn’t much avgas down there, unless you can do an “arrangement” with a club which has it only for its own use, and for that you need to speak good Italian, as I believe you do

Ever thought about an atlantic crossing?
No – 35+ hours in the air, wearing a drysuit, and then you have to fly all the way back
Okay, I see. And on both ends you will not be greeted with > 30 °C and girls in Bikinis serving you Caipis 
Damn… my incentive formula is out
