Following the instructions in the manual, I converted some open source icons to be 40x40px attempting to use them as group icons. The groups icons are displayed as 20x20px in the tree navigation which makes them look very bad. Is there a way to specify a 20x20 and a 40x40 image for the same custom icon? Are we able to use multi-layer ICO files? This is being done on v8.1.0.11.
