So, my old laptop crashed. Got a new one with a much higher screen resolution of 3840x2160. Now the directional and favorites buttons next to the current lister location are very small. See attachment. Looked all over the place in settings, but cannot find how to make them bigger. How do I make them bigger?
One of the new features in Opus 12 is high DPI icons combined with automatic DPI scaling throughout the program. You can see a demonstration at the start of the What's New video:
If you stay with Opus 11, installing one of the "XL" icon sets which have been uploaded to the Icons forum here is another option. This won't be as comprehensive as the high DPI / DPI scaling support in Opus 12, but it will at least give you larger toolbar icons. (If you do do this, but then later move to Opus 12, you'd want to remove the icon set as it would be made much larger in Opus 12, and would not be needed anyway as there are large icons built into the newer version.)
