I think Dolphin and Discover share the "Blue square" base design, while Settings and Konsole share the "Black square" one... I usually misclick these app icons because of this.

NOTE: I know Dolphin sticks to whatever the Accent color is set to. But the default color is that shade of blue, similar to Discover.

Would it be possible to change some of these icons? I'm not a designer nor have artistic skills to do so, unfortunately.

Some ideas:

• Maybe set Discover to be a paper bag or another shopping icon
• Settings could be a gear (wink wink)
• Global settings and System settings share the same icon unfortunately. Maybe these could be different :)
