File > Save Session As …

Keyboard shortcut: none (expert mode only)

Saves the JOSM session (i.e. the currently present Layers) to a file.

This might be useful e.g. to save your work for later continue, to transfer your work to another PC or for bug reporting. Some layer types can't be saved to a session, e.g. validator layers.

Life hack: If you want to start JOSM with a predefined selection of imageries, add them, save them as session an load that session at your next JOSM start. This way you don't have to manually readd all imageries individually.
