"Annotate with revision numbers" link to revision
Created originally on Bitbucket by Anonymous
In "File history" / "Hg file log viewer" dialog, there is a very useful option "Annotate with revision numbers". Hovering over a certain line also shows some more information (user@revision:age "summary") in the statusbar. A further useful enhancement would be to turn the annotated revision numbers or the lines into links that select the relevant revision in the list. (Or add right-click menu entries to open the relevant revision in the workbench etc.)
