About Tab
A read-only info screen — the only tab with no Save/Revert/Cancel row, since there's nothing here to edit.
Version
Shows a version string in the form "Vertexix 0.1.<build>", where the build number increments automatically on every compile. This screen doesn't currently name which edition you're running.
Links
Real clickable links to the Vertexix website and its bug tracker, opened in your default browser.
