+ ==== fb2k::coreDarkMode API ====
+For many components, main issue with implementing of Dark Mode is that libPPUI Dark Mode implementation is *huge* and adds a massive amount of code to otherwise small component DLL.
+Using fb2k::coreDarkMode addresses this - provides interface to foo_ui_std implementation of Dark Mode hooks.
+This allows implementing Dark Mode without size bloat - however, it also means talking to possibly outdated libPPUI that comes with user's foobar2000 install.
+If you use this, you should make sure that your UI works properly with the oldest supported foobar2000 release with Dark Mode, such as early v2.0 builds.
