Collecting new/improved stuff in 5.1 for promo

[Thomas Pfeiffer]

Hi everyone,
I'm sure we can help Sebas and David for the release promo by collecting what 
we've done since 5.0, so I'm starting with what the VDG has done or 
contributed to:
- Icons (added tons of icons to the Breeze theme, plus reworked the Systray 
icons to match the general theme)
- Breeze widget theme
- Look & feel / Megathemes KCM
- Plasmoid alternatives switcher
- Klipper Plasmoid
- System load viewer Plasmoid
- HIG restructuring to improve usability (not exactly a Plasma feature, but 
since Gnome promoted their new HIG with the 3.14 release...)
- Visual glitch fixes

We'll gladly provide more details on any of those points if required!
Cheers,
Thomas
