Discussion about highlighting (MS compatibility issue)

Hi there,

I'm working on an old MS compatibility issue related to character backgrounds:
https://issues.apache.org/ooo/show_bug.cgi?id=24317
https://bugs.documentfoundation.org/show_bug.cgi?id=64490

Problem is that Word uses two kind of character backgrounds called
shading and highlighting, while LO uses only one called character
background. It would not be too hard to support highlighting
separately also in LO (simple character background could be set in
character dialog and highlighting with the Highlighting toolbar
button), but the question is that whether it's worth or not.

One problem with the two background concept is that, when we get a
document with character background we can't decide on the face of it
which character attribute we have. If the users are not aware of that
LO has two different background attributes then they may have some
problem with editing the document:

This problem might be avoided by adding a new default toolbar item for
setting the other background color too next to the highlighting
button, so it will be clear we have two different character
backgrounds here.

Any suggestion on that?

Best Regards,
Tamás
