+====== KDE Plasma Task Manager button width ======
+When turning on Group by Program name but turning off Combine into a single button, the maximum task manager button size decreases.
+I fixed this by editing preferredMaxWidth() in ''/usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/code/layout.js'':
+<code javascript>
+function preferredMaxWidth() {
+    if (tasks.iconsOnly) {
+        if (tasks.vertical) {
+            return tasks.width + verticalMargins();
+        } else {
+            return tasks.height + horizontalMargins();
+        }
+    }
+//    if (plasmoid.configuration.groupingStrategy != 0 && !plasmoid.configuration.groupPopups) {
+//        return preferredMinWidth();
+//    }
+    return Math.floor(preferredMinWidth() * 1.6);
+}
