It started with grizzler when he mentioned that our Update Manager did not function in Plasma 5. When I solved the technical issue I saw that the UM icons looked out of place. So, I decided to flatten the icons and eventually chose to create new icons all together.
Our SolydXK icon is okay as long as you don't make it too small. The use of gradients makes it difficult to shrink the image and still keep it crisp and recognizable. Also, our overall design seem a bit tired and could use some freshing up. No, not a re-design, but more like spring cleaning.
So, I've abstracted the form and colors. No gradients and just a few colors. I've attached an svg file (best seen and changed in Inkscape) with our current logo's and below them the ones I've been playing with. I also added a print screen of the new flat style to see if it still fits together.
I've also attached print screens of the themes and wall papers using the latest flat icon but still with the old background to refer back to what we started with (and because people usually don't like changes...but I do
