first of all sorry if I come back to our Xselection stuff so late, but
the new class branch was quite a huge job form me (I also need to get
to understand what I'm doing before actually doing it, and that
unusually takes more time then the actual getting things done, if you
know what I mean.. :)

Well, me too (I'm a lawyer after all), but I don't want to take
credits for others' job. Anyway I'll respect your decision here.

This seems fine to me.

Well, as far as I know, and if I understand the point you are making,
it is the application that must provide the UTF8_STRING property.
Since we call internAtom with a False, if that application doesn't
provide an UTF8_STRING, xmonad is going to crash - am I right here?
I'm thinking about legacy application some user may be running, and
then she comes up with a bug you cannot even chase..:)
But I repeat it, I may be wrong.

There's a module I contributed, RunInXTerm. I'm wondering if this
function wouldn't be perfect for that module (function to be exported
for other to use) more then in Xselection.

As you know I achieve this result with hxsel from the command line,
but this could be a useful addition I think.
I was also thinking about a prompt (with, possibly, a completion of
available searches) where you type a search engine and a query and
firefox is going to open up the appropriate page. What would you
think? Something like SearchPrompt. This is something I would like to
have (and if nobody does I'm going to write as soon as I'll have some
Once again, sorry for the delay of my answer.
