Fixes
- Copy no longer includes the alignment filler: select-all in a pane and copy (⌘C) yields exactly the file's real content — the gray alignment gaps (where the other side has extra lines) stay out, as in WinMerge.
- Dropping a file onto a pane loads its content on that side (instead of pasting a file:// URL) — just like WinMerge. Works in the blank comparison too.
- Detailed closing dialog: when closing a comparison with unsaved changes, each modified side is listed (path or "Untitled") with its own checkbox — you pick what to save, as in WinMerge.
Install: open the dmg and drag to Applications (replace the previous version).
