Einav is right; in general, UI plugins can extend existing UI,
i.e. add custom tab, show custom dialog, add custom button to
existing tab, etc. See [1] for details.

UI plugins can also hook into some application-wide events,
such as user login/logout, main tab item selection change, etc.
See [2] for details.

[1] http://www.ovirt.org/Features/UIPlugins#API_function_reference
[2] http://www.ovirt.org/Features/UIPlugins#Application_event_reference

What you can do is add your custom button on some existing
main tab with click handler that makes some HTTP call to
trigger the action you need.

If you need to add click handler for *existing* button on
existing main tab, or you want to be notified when current
(active) main tab changes, this is not supported yet. Please
create RFE for this if it's something you'd like in UI plugins.
