I did some photoshopping to try out a few ideas. Not saying they're better than current Haiku or that anything should be changed yet :) 1) http://www.oljud.se/files/haiku/1_border_handles_contrast.png Painted active window border yellow to make it stand out from the background. Also made it flat coloured because it was too distracting when embossed. Increased contrast on buttons and slider background to make objects you can interact with stand out more. Added handle on sliders because they're movable. Tried to do something similar with the resize-corner of the mediaplayer but it looks like crap :P Put X as close buttons (arguments in other discussion). I know it looks a little too heavy so it would definitely require tweaking. 2) http://www.oljud.se/files/haiku/2_flat_background.png Made the background of the menu and toolbar flat because it felt a little cluttered with all those lines. IMO backgrounds should be pretty flat while objects should stand out more using gloss, shadows and/or emboss. There's a potential risk that the menu items are mistaken for labels so this isn't a very good solution, just wanted to see what it would look like. Tried a yellow background, something similar to what Mint does, but it just looked weird. 3) http://www.oljud.se/files/haiku/3_reverse_contrast.png Reversed the contrasts of window border and contents. The reasons for this is that I wanted to reduce focus on the border and increase focus on window contents. I also wanted a little more difference in luminosity between active and inactive tabs. -) And what I didn't do: Rounded corners on anything, because it's too fiddly :)
