* Touching the screen when sleeping will wake up but not change screen
* Removing footways (if bicycles not allowed) to reduce resource usage
* Switching screen will clear the screen immediately so you can know your screen touch has been received
0.24:
* Fix for loading very large files (> 65kb)
* New menu on file selection : reverse path without waiting for file to load
* Fix for files converted from maps2gpx : path was not reduced in size correctly
* Experimental ski mode : have a ski slopes map
* Fix for path projection display when lost and zoomed out

### Preparing the file
You first need to have a trace file in *gpx* format.
You typically want to use a trace file in *gpx* format.
Usually I download from [komoot](https://www.komoot.com/) or I export
from google maps using [mapstogpx](https://mapstogpx.com/). [Brouter](https://brouter.damsy.net) is
also a nice open source option.
@ -48,6 +48,11 @@ Just click the disk icon and select your gpx file.
This will request additional information from openstreetmap.
Your path will be displayed in svg.
Note that it is also possible to just hit the shift key and drag the mouse on the map
to download a map (with no trace). If you want a map, hitting the "ski" checkbox
before selecting the area will parse openstreetmap data in order to get the pistes and
the lifts. Colors will correspond to difficulty levels.
### Starting Gipy
At start you will have a menu for selecting your trace (if more than one).
