Currently it is possible to add an Issue Tracker URL to the project Metadata, but it seems that URL does not appear anywhere?
Please enable display of that information. For any project without an own issue tracker I will add a useful link with a query to our bug tracker to encourage users to help to improve Extensions or to fix bugs.
This will also help to distinguish extensions supported by TDF from the other 3rd party extensions.
Note that some 3rd party extensions even can't be supported by TDF easily because there is not a good way to build them from sources. Some other are too language specific or hard to use. All these should be supported by their authors.
