Would it be hard to enable the full screen mode of Lion? I know, Mac Hg is not an application which would usually been used in fullscreen but e.g. when browsing a huge repository to view changes it could be helpful. And if not do not want the fullscreen mode one do not have to use to.
After opening Mac Hg the user sees the welcome screen. The welcome screen is nice but when working not that useful :). I thing it would be useful if Mac Hg shows the repository last viewed (when Mac Hg should open the file last opened).
