You can reorder, show and hide lanes on your journey maps as you like.
Please keep in mind that anything you do will also influence the exports. This also allows you to quickly customize exports.
To keep a reference to specific lane while working on a journey map you can pin one or more lanes. Click on the cogwheel on the left hand side of the lane and click on "Pin/Unpin lane".
Simply drag and drop lanes to rearrange them as you like. Also you can use the cogwheel on the very left hand side of the lane to move the lane upwards or downward.
Show & hide lanes
Use the cogwheel on the very left hand side of the lane to show or hide lanes on the journey map. If a lane is hidden, it will not be on the exports you create.
You can also delete lanes by using the cogwheel on the left hand side of the lane. Please note that there is no redo for this action. You can also simply hide the lane if you don't need it for now.
