Is your feature request related to a problem?

Currently, the game will arrange the list of available charts in order as how they were inserted in the simfile being parsed. This can result in out-of-order lists relative to the level/meter of charts.

Describe the solution you'd like

For gamemodes that utilize the Easy/Medium/Hard/etc difficulty types such as dance, the levels should be ordered from lowest to highest if there is more than one chart with the same difficulty. For gamemodes that do not feature difficulty types, such as pump, all charts from the same steps type (single, double, etc) should be ordered from lowest to highest, independent if the simfile also contains different difficulty types.
