  - Fixed a huge performance bug that slowed moving nodes left.
  - Expand/Contract commands now operate on the selected tree.
  - Sort Siblings command can now sort top-level nodes.

Quote of the Month:
-------------------
I gave Leo a try a while ago, but did not recognize its strengths as an
outliner. In April 2003 a gave it another try. And when I saw in the online
help mentioning clones almost in passing (you got to emphasis this much
more!), I knew: This is it.

If you are like me, you have a kind of knowledge base with infos gathered
over time. And you have projects, where you use some of those infos. Now,
with conventional outliners you begin to double these infos, because you
want to have the infos needed for the project with your project. With Leo
you can do this too, but if you change text in one place IT IS UPDATED IN
THE OTHER PLACE TOO! This is a feature I did not see with any other outliner
(and I tried a few). Amazing! Leo directly supports the way I work! -- F.
