Hi, I find there is a `tile` command. After I enter the tile mode, the zoom is global. I guess `tile` is implemented by transforming the active models in the global scene explicitly. I wonder if there is a way to have the zoom independent for each model, similar to the grid mode in PyMol. A further question, more from a developer's perspective, is whether having multiple 3D rendering viewports in ChimeraX is possible. I imagine each viewport can have its own active models in the scene and its own camera. Different cameras and other operations might be synced upon users' request. This video (https://youtu.be/7KZ1P-nPav8?si=Z1hiBBuRiWop2WFC) demos the feature (in an old version of Houdini).
