Question about kerning and opentype features (ligatures)

Hello!

My name is Ivan Ivanov, an administrator of the Wiki and Documentation team of Ubuntu GNOME.

I am really in love with LibreOffice and the open-source project. The new version 4.3 is awesome and good-looking.

But I have a question about the option "Pair Kerning". My hobby is typography, but I hate kerning and I always disable it if there is such option. But the option in the most recent versions of LibreOffice does not work. I disable the "Pair Kerning" option, but kerning is still enabled. The last version without this bug (where you can disable kerning) is 4.0.6.2. All versions after this have this bug and kerning can't be disabled, which annoys me...

And the second thing is about some opentype features. I hate ligatures, too. There are many fonts with ugly ligatures and I prefer seeing "f" and "i" instead of the ligature for example. In LibreOffice 4.0.6.2 ligatures are not enabled by default, but in 4.3 for example ligatures are automatic to form. I want to disable this, too.

I want version 4.3, because it is really beautiful in design and perfect in functionality, but I want to disable kerning and ligatures. How to do this?

Thank you!
