What is synchronized split scrolling?

In Split View, horizontal and vertical scrollbars are locked across both panes with an event-syncing lock, keeping corresponding code lines aligned even when scrolling rapidly.

Can I export a valid Git patch file?

Yes! Click "Copy Unified Git Patch" or "Download .patch" to generate an RFC-standard unified diff (--- a/original +++ b/modified) ready for "git apply".
