+|`projections`                        | A list of map projections to register, in the format `{"code": "<code>", "proj": "<proj4def>", "label": "<label>", "precision": <decimals>,"format": "<format>", "swapLonLat": <swapLonLat>, "addDirection": "<addDirection>"}`. By default, `EPSG:3857` and `EPSG:4326` are registered. `format` sets how coordinates are displayed in map viewer, `dm` shows degrees and minutes, `"dms"` shows degrees, minutes and seconds, `"decimal"` is default. For non degree crs `"decimal"` is used even when other option is set. `"swapLonLat"` changes order of coordinates when `true`, default: `false`. `"addDirection"` adds direction letters to coordinates, `"prefix"` adds it before, `"suffix"` adds it after coordinates, default is `"none"`. |
 |`qgisServerVersion`                  | The QGIS Server major version in use. Default: `3`. |

 |`storeAllLayersInPermalink`          | Whether to store the full layertree in the permalink data, rather than only local (i.e. redlining) layers. If `false`, remote layers are re-queried from the respective services, if `true`, they are statically reloaded (meaning restored layers may be outdated compared to current service capabilities). Default: `false`. |
