Here I introduce my first KDE Plasma theme, very humble artistically but, I believe, most usable.
What it do?
It do make Plasma panel usable:
-it do make the task buttons clear.
-it do make the foreground, background and attention requesting tasks clear.
-it do make the pager clear and give big button to tray.
-it don’t confuse user with transparency.
After trying out so many overly artistic themes and finding that none of them is usable for me I made this one. It is lacking in artistic expression, but who cares. Now I can finally differentiate between things in on the panel. For the first since adopting KDE 4.
