Created attachment 109360 [details] Large and Small icon for the same stuff in the "Panel" This happens on Fedora 27 KDE: I have added the icon for LibreOffice Calc to the "Application Launcher" as well as to the "Panel" (as shown in the screenshot). The icon was added by using the option in the drop-down menu One can at that point drag & drop the "Spreadsheet" icon from the "Application Launcher" to the "Panel". At that point, you get an secondary icon for "Spreadsheet" which is smaller than the one added via the drop-down menu and which also has another style of explanatory pop-up note. This should probably be unified if there are no other pressing things to do. (I have only tested this with the "Oxygen" Icon Theme btw.
Couple of questions: 1. Can you test with Breeze, just to make sure the same thing happens there? 2. What you are calling the "Application launcher"... is this a Quicklaunch widget, or are those apps that you pinned by right-clicking on their Task Manager buttons and choosing "Pin" or "Show a launcher when not running"?

Hi Nate, The same things happens, see attached screenshot. Concerning the designations: The "Application Launcher" is what would match the "Windows Start Menu". It's the menu that pops up when you go the "start button" (in Fedora, the blue button with the barred integral sign). (Sorry about my Homer Simpson level of explanation, all the KDE widgets have names but they not fully unintuitive. And it's all about finding stuff and sending messages to stuff and getting notifications from stuff - I feel a new approach at GUIs is needed. No, not Metro! Anyway...) The fact is that the two icons in the "horizontal bar across the bottom of the screen" (i.e. the "Panel") are two different things. -> The small one, obtained by dragging the "Spreadsheet" icon from the "Start Menu" can be "unpinned" but that's it. -> The large one, obtained by right-clicking the "Spreadsheet" icon and selecting "Add to Panel" cannot be "unpinned" but has "properties". Implementation details are probably bubbling up here, like if one element is represented by a symlink and the other a configuration file.
This isn't quite correct. There's two options, "Pin to Task Manager" and "Add to Panel". Those do different things, and yes, they result in different icon sizes. Task Manager icons are smaller because of the task button frame. Standalone icons don't have a button frame and have more space available to them.
