configured to a large folder as the changing data set causes the<br />
view to do a large amount of costly work.</p>
<p>A 7x6 Folder View pointed at /usr/bin would block Plasma during<br />
startup for anywhere between 1-4 seconds depending on disk caches<br />
(on a SSD). Now startup is hitch free, and even listing completes<br />
much faster without the view slowing things down.</p>
<p>The widget is set to busy while listing.</p>
