Using album mode
Album mode works like a notebook: each photo, or a small group of photos, lives in its own cell. Reorder a cell, edit its caption, or apply an adjustment, and only that cell re-runs — the rest of the album stays exactly as it was.
Select a run of cells to move them as a block, the same way you'd move a range of cells in a spreadsheet, rather than reordering one photo at a time. Captions and tags attached at the cell level apply to everything in that group until you split it apart, at which point each photo keeps the caption it inherited.
This cell-based model is the same execution model used by notebook tools like JupyterLab — cells run independently and only recompute what actually changed, which turns out to fit photo albums just as naturally as it fits code.
