Detect/store special changes and vizualize appropriately, eg. a move/duplicate (ctrl-x/v/v). Assume nr changes are smooth/fit graph along z. For images, morph 'ed (XD)! For colors, smooth transition them! (or have it snap, depending on ctx). The trail interface, while also amazing in VisionPro/VR, allows for a quick intuitive sense of the sheet's evolution through time, space, collaborators, and sections. Combine with LLM's or other to write telescopic text summaries of changes. Non-linear timescale to have it based both on time and change density (cognitive wise, not necessarily data-wise); ability to affect this parameter along with the space-between change-regions to create clearer clusters of editing sessions, or parameter for conceptual/spacial regions, to separate edit history, recursively, into more specific areas of interest. (eg. if code, how has this functionality changed? keeping it in center while files surrounding content may move around it, while its origin story unfolds as it splits and merges across locations (+ utilizing data flow/dependency graph, to bring surrounding functionality ctx in the periphery.
