Yes, I've actually got some getLegendGraphic improvements about to be checked in (optional font anti-aliasing, etc).
WRT a specific rule choice not appearing with a title, I think this is a good thing. If you know the rule name (and are asking for exactly ONE rule) then you know enough to give it a good title.
With the latest changes to the legend graphic code I could definitely make this the default, but have an option to change it (&LEGEND_OPTIONS=forceTitle:true)
Michael, would something like the above option make sense to you?

Subject: Re: [Geoserver-users] GetLegendGraphic has no title when there is only 1 Rule
Not sure what to do about this one. I would not be against changing the
behaviour. Perhaps add another parameter to contol it. Something like
"&title=true"
Saul: you should just did some legend graphic improvements didn;t you.
Whats your opinion on this one?

which uses http://transit.frumin.net/SLD/trx_lines_multi.sld (identical
to the one above, but with an added Rule to draw the line in blue) has 2
legend entries, both with the correct title.
I imagine this is the same bug as I sent in before whereby when you
specify a Rule=XXX in your GetLegendGraphic the title goes away, but
since it has a slightly different genesis so I figure it's worth reporting.
thanks,
mike
