I don't know what I did, but suddenly the calender view is displayed in 
the whole window. Folder pane and Lightning pane is gone, and I can't 
figure out how to get them back. I can get back to the inbox by closing 
Thunderbird and then open it again, but the folder pane is still not 
shown at the left. And if I change to the calendar, I'm stuck again ...
... I found out, it was collapsed. But there is no way to see this, and 
no way to see, how to get the pane back again. I think this is going to 
be a major pain in the behind for ordinary users. At least there need to 
be a grip, when it is collapsed.

I've filed a RFE on that.

However, there is an extension that provides a button etc.:

No, it's two different things. Both needs to be taken care of in a 
future version.

This open/closes Lightning in the sidebar. If one has many message 
folders, it is nice to be able to turn off Lightning in order to see 
more folders.

Thanks! I will be sure to write about this on my Sunbird pages:

(sorry, they're in danish and not yet updated to version 0.3)

This on the other hand is more serious. If one tries to make the folder 
pane smaller, it disappears totally. And there is no indication that it 
is merely collapsed.
I clicked at the splitter by accident, so it took some time to figure 
out what had happened. I'm sure ordinary users will never find the 
reason, and that they will have to uninstall Lightning in order to get 
the folder pane back.
Actually the same behavior is in Thunderbird without Lightning, but the 
pane does not disappear until the pane is very small. With Lightning one 
just have to change the size with a millimeter, and poof!
Kind regards

If the pane width gets smaller than the minimum width - the width
that is required to display all elements inside the pane - the pane
collapses.
With Lightning installed the three buttons 'New', 'Edit' and
'Delete' in the Calendar tab forces a minimum width of about 270
pixel on my system.
Workaround for people that want a narrow pane:
Hide all buttons using userChrome.css style rule:
  #ltnCalendarButtonsBox { display: none !important; }

Yes! I just installed Lightning and found myself wanting to do that
(have like 8 accounts and small monitor :) ).
Is there any option in about:config that controls/disables the Lightning sidebar?

It's a lot easier if you just install the extension ltnToggler, that

You can enable or disable the Lightning sidebar using an icon or the 
short key F9.
Thanks! I know in my post I said 'sidebar'. My bad, what I really meant
to say was:
Is there any option in about:config that controls/disables the Lightning
*Calendar* in the sidebar (but keeping the todo list and agenda).
You can do this via CSS-Rule in chrome/userChrome.css file
[http://kb.mozillazine.org/UserChrome.css] in your Thunderbird
profile. Add the following rule:
    /* hide Minimonth */
    #ltnMinimonthBox { display: none !important; }
/Stefan
That worked perfect. Thanks!
Tb 1.5 removed grippies, so this extension 
https://addons.mozilla.org/firefox/2242/
was created. I have modified it for myself to show a grippy for the 
Lightning splitter, it's not hard but not necessarily easy either.  Tb2 
brings grippies back for the Message Pane and Folder Pane, but the mod 
also works for Lightning in Tb2.
If you really want the grippy now, let me know and I'll post how; the 
other likely better method would be to use the userchrome.js extension, 
but I just modded the extension.
I've also made quite a few mods in css to style Lightning, to remove 
wasted space etc.  Space in the Folder Pane is very precious..

It was not for myself, but in order to not alienate ordinary users. And 
I guess that description will not be for them.

Indeed. The first thing I did, when Lightning was released to my OS 
(where the pane is even wider than in Windows), was to use the 
css-trick, which Stefan wrote about earlier in the thread, in order to 
remove the buttons.
