Created attachment 7913 Proposed patch As discussed in: https://github.com/shimmerproject/Greybird/issues/224 Currently it is only possible to set values to listview-icon-size and icon-size properties. We can take advantage of css styles to distinguish the grid and list modes of tabwin, thus allowing themers to apply distinct styles to each mode. The proposed patch accomplishes that, but feel free to change classes names.
LGTM.
