There was a problem hiding this comment.
Thanks @alexbruy 🎉
I have few suggestions:
- let's set
fidfield to be hidden - let's have only 2 decimal places in the
total_distance
I also found this issue:
- make basic project through plugin
- add tracking
- add new feature to tracking layer (in plugin)
- after saving the layer, this feature is not visible on map
- I do not even see it in attribute table (maybe missing commit to layer?)
then, I could not sync the project because of

User can enable or disable tracking as well as choose desired tracking precision. On the first activation plugin will automatically create a new GPKG with the tracking layer and add it to the project.
This reverts commit c627ed6.

Add a new group to the Mergin project properties widget to setup tracking. User can activate/deactivate tracking and select desired tracking precision.
Tracking configuration then saved in the QGIS project file and will be used by mobile application.
If this is a first activation of tracking a new GPKG file called
tracking_layer.gpkgwith aLineStringZMlayer will be created in the Mergin project folder and added to the project. Note, we require project to be saved before enabling tracking as otherwise we can not determine where to put GPKG file.
