Thanks for the reaction.

Yes, I am using a combination of refiling, tags, links and searches, and
it works. However, it looks fragile and ad hoc. As far as I see it, some things
just naturally can be classified using several hierarchies, like
something that concerns project A, was first discussed at meeting B and should
be consulted with person C. Where should I put it? I would like to be
able to find it in all three places. Moreover, I would like to prepare a
meeting with person C, make notes on the subject while we talk and then
have the notes available also when browsing the hierarchy of project A. 
I have to choose one of the three trees and use tags or whatever
other means to make it visible in the other two trees. If I forget to
tag it, it is lost, very difficult to find again.

Even with such TODO labels, how do I sort them into the order I want?
With links, it is easy, I just link all the issues I want to discuss to
the meeting subtree, in the order I want.

Thanks for your help.
