For graphics designer it is a very much essential fearure. Sometimes I need to boot gnome so that I could see all the icon preview. As far as I know Konqueror has the feature. If you got some time kindly consider adding this feature.
Do you have kio-extras installed? Do you have SVG previews enabled? (check in Configure Dolphin -> General -> Previews)
Yes, I have kio-extras installed and preview enabled. But that previews png, jpg, doc etc. But not svg. Is it supposed to preview svg?
Yes. Are you sure you actually have the SVG entry checked in the Dolphin settings?
Sorry, I didn't enable it. Thanks for taking your precious time and reviewing my problem. The issue can be closed.
No problem :)
