Yes you and I are pushing the edges with project and build plugins
because we are not adding new functionality but improving something
that already exists so need to integrate with it.
My plugin is a bit

Yes, but it tends to be a specific function for a specific plugin, not
general capability, there seems to be some resistance to thinking
about them as general capabilities.

Yes, I agree, I was more thinking about providing general capabilities
rather than a wide API. It may mean some re factoring of Geany
because at the moment many of the restrictions are hard coded in low

Well, really why not? I someone wants to make it work differently
because they like it that way, why can't they. If you don't like what
a particular plugin does, just don't use it. :-)
