There has been recurring discussions about making NetBeans look better on HiDPI (retina) screens. This is a large umbrella issue, touching all three major operating systems (Windows, Linux, and MacOS), with many subtasks involved. I have created a Confluence page which summarizes the current state of HiDPI/Retina on NetBeans, and the high-level TODOs:
https://cwiki.apache.org/confluence/display/NETBEANS/HiDPI+%28Retina%29+improvements The biggest unknown here is probably how to replace the old bitmap icons (several thousands, or at least hundreds) with scalable equivalents. But before that is done, SVG icons must be supported from the NetBeans Platform APIs (ImageUtilities, Node etc.). -- Eirik
