Add additional informations to the structure view

[spechto]

Describe the feature and the current behavior/state

It would be great if it were possible to add further information to the structure view. In the same way as is already possible with the regular expression for the TODO comments. You would need a field for the name of the node in the structure view and a field for the corresponding regular expression. That would be it, I think.

Who will benefit with this feature?

In some cases it could be usefull to have an overview of special commands like \figure, \bibitem or \cite. When defineing own special latex commands the system would be very flexible to handle it.
