Copy track folder line style from another folder

The track-folder-line-style can be quite a complex beast to setup

• line+color+transparency
• pattern+color+transparency
• pattern
• coloring mode
• width
• units
• outline+color+transparency
• close line & fill color+color+transparency

My suggestion is to add a dot-dot-dot menu item that allows you to copy (adopt) the line style of another folder. Each year I have a new "group" named as the year, with a folder for each major recording activity. For example 2023 > walk, 2023 > car, 2023 > group-ride etc. It would save so much time to just "adopt" the existing line styles instead of setting up from scratch.
