plasma5 and kde4 settings: what to synchronize

[Marco Martin]

Hi all,
One thing that seems very requested, is to try to synchronize as much settings 
as possible between plasma5 (and kf5-based apps) with legacy kde4 
applications.
Right now it's correctly handling some things when changing settings from 
plasma 5 systemsettings:
* colors
* fonts
* icon theme

there are many other settings that are "global for all applications" that are 
not synced yet, and I think we definitely want to have them eventually (one 
way to do it terribly in bulk would be to just sync the kdeglobals file 
probably, but that's probably waay too much).

other things i can think about is some stuff in the fine tuning section of 
qstyle configuration, some fine tuning stuff in the icons configuration, and 
one I really don't know how to solve:
widget syle: we want to be sure the chosen style has also a kde4 version, so 
the only way to be really sure would be doing a kde4 application to do it?

Any comments (or solutions for the widget style sync)?
can someone think about other things to synchronize that aren't taken care of 
yet?
