You have a menu on the second screenshot showing a menu.  I don't seem to have 
this menu, either.  How did you get that?

There is no indication that there can be columns when there is only one.  The 
text shouldn't say that there are columns when there aren't any or should say 
that you could have some and how.  And see above, I don't have this menu.

When you just want to add the size field and not play with all the buttons, 
it's only confusing.  And why are there even fields shown when you can't use 
them anyway?

I like flexibility, and I think there is quite a gap between the design and 
the flexibility.  How to get the size displayed is probably all obvious to 
someone who designed/programmed it and maybe someone who just likes to play 
with all the buttons while it is nothing but confusing to the point of being 
impossible to someone like me who just needed to quickly pick some messages 
amongst many while in the process in doing something entirely different.

That is precisely what I wanted to avoid: play with all the buttons.  But I 
can do that now ...

That's ok, I don't care about icons.  Without text, I never know what an icon 
is for anyway.  They basically all look the same to me, especially the tiny 
ones you can't really see anyway.  I think I picked this one only because it 
makes the mouse pointer better to see ...

Well, I can drag the fields and it has no effect, and I'm not getting this 
menu.  Maybe it works better when I clone a theme ...  Where would I find the 
log files?
