Simple Multi-Chart Sync (link charts by time)

Problem
When I analyze multiple chart views and indicators for the same instrument, I must scroll/zoom and replay each chart separately. Time alignment drifts, crosshair/timestamps don’t match, and with three or more charts the manual syncing becomes slow and error-prone—especially in post-session log/replay work. This makes it harder to spot edges that occur at the same moment across different views.

Proposal
Add a simple “Link” option to selected charts of the same instrument so they move together automatically: synchronized time axis (pan/zoom), shared crosshair, and synced replay/step. When I move or scrub one chart, all linked charts align to the same timestamp and window, letting me compare different views/indicators at the exact same moment, find multi-confirmation edges faster, and save a lot of time.
