A very useful plugin. But unfortunately I've encountered some problems.
(1) As probably intended, it is possible to import the Spots from another server using the standard 'WordPress Importer' plugin. When creating widgets on the new server a selection pulldown appears which allows the selection of one of the imported Spots posts. When saving, the content is pulled from the Spots post to the widget properly, but not the title. The title has to be copied manually.
(2) Changing the title of a Spots post does not change the title in the associated widget. This is independant from imported Spots posts.
Especially the second feature would be great, as it allows users to work on the Spots posts and not to change the widgets directly.
