Created attachment 130728 [details] djvu file and okular file in dolphin In Okular, when you try to save after adding annotations to a file format that doesn't support them like .epub or .djvu, it prompts you to save your changes in a .okular file. This is a very nice feature. Unfortunately though, .okular don't show previews in Dolphin which is inconvenient. It'd be really nice if previews were added for .okular files like they exist for pictures, videos, documents, blender files, krita files, etc...
