+- edit traces by adding, inserting, moving or deleting track points
+- reverse traces
+- add or change the timestamps of a trace
+- view, add, edit and remove waypoints
+- reduce the number of track points
+- view and rework the structure of the file
+- automatically add elevation data to traces if missing
+- merge multiple traces, extending time, heart rate, cadence, power and temperature data where needed
+- extract segments from traces and perform any other action while maintaining the segments' structure within files
+- save the result on your computer or to your Google Drive™ to get a shareable link and embedding code

+## Mapbox Community 🤝
+
+[Mapbox](https://mapbox.com) is the company providing some of the beautiful maps on this website. They created a program called [Mapbox Community](https://www.mapbox.com/community) to support non-profits, educational institutions, and positive-impact organizations. We are very lucky and grateful to have joined this program and to benefit from a great discount on all API rates.

+## Help keep the website free (and ad-free) 🙏
+
+Each time you add or move a track point, we make a request to our servers to retrieve a route on the road network. We also rely on APIs from Mapbox to load beautiful maps, retrieve elevation data and process geocoding requests (looking for a place in the search bar).
+
+Unfortunately this is very costly so if you like the tool and use it frequently, please consider making even a small donation so that this website can stay free to use and ad-free. Thanks for your support!
