Shape 5

I would like to see a tooltips extension with the following functionality:
1 Tooltip displayed using S5 effects when the mouse pointer hovers over a concealed link defined using custom tags
2 A content plugin to automatically detect a term to be defined and insert the pair of tags when editing content
3 The content plugin should work in the VM product maintenance page as well as the standard article page
4 The tooltip should work inside the VM component as well as the content component.
There are a number of these extensions around but none of them seem to work inside VM and an extension with this functionality would be great.
Thanks
Phil
