added starting and end position as sorting option

[jumlauft]

Addresses issue #204 to add more sorting options for tricks Let me know if you have more ideas for sorting options

Nice, thanks a lot for your contribution! (sorry for the late reply... 🤹)

More sorting options could be:

• year (newest tricks at the top)
• average difficulty of combos (maybe rounded?)
• max difficulty of combos
