Description khbellgardt 2003-12-03 08:26:57 UTC
At present subscripts and superscripts are shown at the same horizontal position
relative to the indexed character. This looks well for normal fonts. But for
italic fonts the subscript should be shifted left to have the same distance to
the indexed letter as the superscript.

At nice-to-have feature would also be to have an option in the dialog
Format->Spacing->Category->Indexes for setting the horizontal (default) spacing
for subsscripts and superscripts.

MRU->TL: I think, this could be a cool "nice to have". We could eye
this for the successor of OO 2.0; what do you think?
Comment 3 guido.pinkernell 2004-02-03 15:23:47 UTC
I think you should eye this. Couldn't you make it earlier than post2.0?

It starts already with often used function names like f_t.
The space between the index and the italic f is just too large.
Comment 4 thomas.lange 2004-02-18 09:24:10 UTC
Probably not. There are already some features and quite a lot of other more
important fixes/enhancements to be done for linguistic and Writer API...
But I will keep an eye on it. The chances are very slim though...

I really doubt my report is a duplicate, but just in case:

Better alignment of apostrophe:

' is so far away from w that it looks like two symbols instead of one (I sense 
of meaning).

Comment 9 toresvn 2008-12-22 10:14:20 UTC
The problem occurs not only in horizontal position! Please see the following
link: (official OO.o forum)
or see the 2nd attachment (this issue, Mon Dec 22).

1. spacing between italic and nitalc characters
2. subscripts / superscripts cause the waste of space in paper
3. underbrace causes the waste of space in paper
... etc.

In comparison with MS Equation Editor (or MathType), OO.o Math is in lack of the
ability to 'move' elements arbitrarily; see examples in the link.
