Indeed.  But believe it or not, there isn't a zoom function in
https://www.jqueryscript.net/tags.php?/image%20zoom/ that does exactly
what you want, zoom an image to 100% when clicked. Most of them show a
magnifying glass over the image, the minority that pop up the full
image don't scale it to 100%.  Well they do, but only if it fits
comfortably on the screen to start with.  I guess it wouldn't be so
hard to write one, but hard to believe there's not one that meets such
simple requirements when there's 50?+ to choose from.

My present plan is to put lots of screen shots on various pages by scaling 
them to a small size, with a reminder to readers that they can view the 
full-size version using the "view image" feature in their favorite 
browser.  The present way is too clunky, imo.

Leo's tutorials should benefit from screen shots.  For example, it would 
simplify the discussion of @button.

Leo's home page uses this technique. It now reminds viewers that they can 
see the full-sized image.

I think pictures would work better.  I've created a project called 
"Screenshots tell the story" as a partial remedy.  This is first on my 
list.  It will use Joe Orr's pictures and movies 
 to describe Leo.

Ready to release 5.8 final?

There seem to be no significant bugs reported against 5.8 b1.

Matt, are you good with releasing 5.8 final?

Nodes can't directly contain children that are clones of its parents.
That's a fundamental limitation.  However, the relation "is a parent of
node x" can easily be created, for any node x, in the usual way.

If you do this often, you might want to use uA's.  "Mark" the desired
parents, for any x, in x.u['parents'], using a script, or by hand. Now you
can create the relation (organizer) node for "the parents of x" using
another script.

HTH.

Sounds like a platform-specific issue.  You script works on Windows.

All output eventually goes to LeoQtLog.put, which ends this way:

w.repaint() # Slow, but essential.

I suspect the Mac version of repaint is being "clever", which is neither
helpful nor correct.  You might try this script, but please use rev e9a020b
in devel.  It properly inits the logWidget ivar, something that was always
promised, but never done until now:

@language python
import time
w = c.frame.log.logWidget
for lines in g.splitlines(p.b):
g.es(lines.rstrip())
time.sleep(1)
w.update()
