lazygit's diff panel is line-based. Would there be interest in an optional semantic diff view that groups changes by entity, e.g. "modified function X", "added class Y", "removed method Z", so you can scan what actually changed at the function/class level?

This could be backed by sem, an open-source (MIT/Apache) entity-level code tool. It emits JSON over a stable CLI (sem diff --patch --format json) across 26 languages via tree-sitter, so it's a clean subprocess call. Another tool, plannotator, already renders a review UI from this exact output.

This might fit as a built-in optional panel, or even just as a documented custom command. I maintain sem and am happy to prototype either. Would a semantic diff view be of interest?
