Since a template must be placed in a layout and there is no UI for managing templates otherwise, I keep at least one instance of every template in a dedicated "Templates" layout so I can quickly(ish) find and update my templates.
I dock my Templates layout in the lower right corner of the editor, sharing space with the Tilemap and Layers views. It's clunky, but it's the best workflow I've found for managing template settings.
But whenever I reopen the project, I lose my docked Templates layout and need to re-dock it. This happens no matter which secondary slot I dock the layout in, as far as I've tested.
Is there some way to preserve the editor docking layout for a project? It's frustrating having my editor reset every time I reopen my project.
