Changeset listing does not show bookmarks.
When you browse to the changeset listing page of your repository ( https://bitbucket.org/clb/knet/changesets ), it doesn't show labels of the bookmarks on the changesets.
It would be useful to show the bookmarks as well in a similar way branches and tags are shown. For example reference, TortoiseHg uses this kind of visualization http://clb.demon.fi/dump/BranchParents.png (please ignore the red paint drawings in the image, the screenshot was taken to report another bug in TortoiseHg). In that view, you can see two bookmarks 'master' and 'latest', which are shown in blue text, on a yellow background.
