[rework docs] questions part one

[Uwe StÃhr]

I don't understand the sense of the menu Edit -> Open/Close Float. This 
menu works only when the cursor is placed before an inset (it also works 
for footnote insets), but not when it is inside the float. And 
opening/closing an inset goes much faster by a mouse click than by a 
menu. In my opinion this would only be useful if it opens/close _all_ 
insets at once.
So what is the real usage of this menu?

What happens in LyX 1.4.x with the error boxes. I read they disappeard 
there. But how is the error handling managed?

Spellchecker:
As I remember LyX offers once the support for pspell. Is it gone? Why?
  In the current version of the UserGuide I found a lot of 
ispell-specific stuff that I would get rid of. Does the problems with 
ispell described there still exist? Or does everybody replaced ispell by 
the "newer and generally better aspell"?
  In the preferences I can choose between aspell, ispell and hspell. 
But as personal dictionary I can only set an ispell one. Why?

thanks and regards Uwe
