Quick Look doesn't seem to work (see attached screenshots). The icons of the SVG files on the desktop are all generic SVG icons. When the spacebar is pressed to have a Quick Look, the same generic icon is showed (but larger). No real preview of the SVG files available.
Gapplin version 1.3.1 MacOS 10.13.4
I experience issues with Quick Look as well. For me the loading indicator is displayed rather than the default SVG icon.
