5.7 update:
All images crushed with pngquant. 40-70% reduced file size, also easier on the device's ram.
Changed the camera grabber. It is now properly display as the camera grabber image, and not in the barbottomlock anymore.
Removed the square icon sets.
Added 438 new glyphs in the unsorted directory of each sets. The total count is now (!)1188(!) icons. Both application specific icons and generic have been added.
Added WeatherIcons for each sets.
As always, if you customized the original icons theme dir (picking icons from unsorted and creating bundles), then make sure you backup your folder, just in case.
