I've been looking for ways of selecting nodes by size or by custom attributes (i.e. Level, Category, etc).
The Find and Select Elements tools have no apparent mode of selecting by custom attributes. This means I'm more or less compelled to structure node maps by colour, then use the fill color selector. That raises its own issues, as the Colorize tool seems to generate random colours for a given node, rather than assign based on an attribute.
I had thought I might be able to map a custom property, but those aren't selectors either.
So, how might I find/select based on attributes like node size?
