Comment 1 for bug 1155024

Handling whoami seems to be a bit tricky as there might be multiple branches used in a single workspace.
Some ideas:
1) It is quite convenient to have a separate setting on a per-workspace level that is unrelated to stored bzr settings as it is possible to use different identity for each workspace. I do not think we should change global whoami setting from bzr-eclipse.
2) A new 'whoami' action might be added to Team menu to view/change the settings on a per-branch level
2) id/email field in preference page can be by default populated with global whoami setting. If nothing set, bzr-eclipse should fall back to system username. Additionally, there can be a checkbox to disable the field. When it is disabled Bazaar will decide what to use based on whoami settings in particular branches/projects or global whoami settings.
