Integration trails of region on trailforks like a layer

Trailforks offers downloading trails o region e.g. 

https://www.trailforks.com/tools/garminmaps/

It would be a great and powerful feacher for TWONAV to integrate  that by the way that you can donwload one region with its database of its trails and use it like a layer to select, follow o plan excursiones. It is very useful for example for its Difficulty Rating of trails and its describtions.

Trailforks offers up to now 863,208 km of 424,404 trails in 123 countries!
