I could see this working it was somewhat like the Labelling(new) engine
dialog, where you could quickly change the current layer's symbol,
possibly opening it by clicking on the symbol in the legend. That way if
you have multiple symbols you can edit each quickly.
Not + for adding this direct symbol dialog opening but I would leave the
ability to reach it in the properties too.

Both, though for the initial tree I suggest groups based on folders
(symbol sets), for symbols that are not part of sets but them into
general categories (this is the current approach on the osgeo svn for
This is what the idea I proposed a while back of embedding tags in the
svg xml is all about. It would allow a symbol to belong to multiple at
the same time. Also I would encourage you but a box in the interface
that let's people type names of symbols, eventually this will be used to
search a local tag database or query a web interface to find matches.
