To support easy editing of NBTwiki pages, I have implemented an inline editor. The inline editor appears if the user double click the text; like this:
Clicking the green button will save text changes. And clicking the red button will discard the changes.
The editor in action:
The editor is builded on code from the quickedit plugin. Compared with the quickedit plugin, the inlineeditor supports locking/unlocking of pages, an editor toolbar, and better security.
