Not so long ago, we had #140 solving bugs regarding airfoil implementation.
It's true that now rocketpy is dealing very well with these non-flat fins, however I feel we could implement some plots in rocket.py file to show to the user.

Some of them could be:

• Simple plot of airfoil data the user inputed by addFins() method
• Derivative of Lift coefficient by angle of attack

But of course

If you double click a .mfmc file from file explorer, it opens your last used file, instead of the opened file.

Steps To Reproduce
Steps to reproduce the behavior:

1. Save a MobiFlight Configuration (Config 1)
2. Save a second MobiFlight Configuration, or save changes on an existing one (Config 2)
3. Open the first Configuration (Config 1)
4. Last used configuration shows (Config 2)

Hi, Just wondering if it's possible to call up a chart from https://www.chartbundle.com/qc/ while in-game. It would be so nice to not have to pre-populate the charts folder. Maybe right-click on an airport on the map tab gives you the option to load its chart.

Thanks!
