It's hard to extend / customize the action buttons used when editing in-place

The action buttons used when editing in-place are loaded asynchronously. If someone needs to add a new button or hide some of the existing buttons it has two options:

• do it from the server, by customizing editactions.vm
• do it from the client side by catching the moment when the action buttons are injected

Unfortunately the second option is not easy to implement because there's no event triggered when the action buttons are injected into the page. The practice, and what extension developers expect, is to trigger an xwiki:dom:updated event.
