New app looks nice, but issues: Map STILL aligns True rather than Grid N. Please change. List of saved routes uses too much screen space so hard to scroll. Need an option not to show the map, or make it smaller. The icon to centre the map on current location changes the zoom. Please don't change the zoom, leave it where the user has set it. But it does look nice.

Been using the app for months to plan and follow hikes. I still carry a paper map around in case of emergencies, but I haven't used it since installing the app. The app is just so much more convenient. One feature I would like to see is the ability to add nodes/waypoints anywhere on a route, rather than just at the end. I'm surprised to see so many people having performance issues with the app. For me it starts up instantly, has never crashed and doesn't excessively drain my battery (Pixel 5).

Update: Loads of GPX file related features added to the app - great work! I'd love to see a feature to automatically create a route. It would be possible now snapping works everywhere! Select an activity (Maybe start with walk, run, cycle), select a terrain type (road or trail), select a distance, select loop or through-route > generate! This would be amazing! Leaving at 4 stars as there are some reliability issues with the app itself, it needs optimisation, but you can work around mostly.
