+31.03.2011:
+        * Feature: Support for custom LADSPA DSSI GUIs, such as those generated by FLAM. (p4.0.19 Tim)
+        - Initial support. TODO: Refine how a particular UI file is chosen - uses first one found for now.
+          Also may need to support multiple choices if multiple lib-level and/or plugin-level UIs are found.
 27.03.2011:
         - Fixed end/off-screen selections not being drawn in midi controller graphs. (Tim)
         - Reverted Midi Track Info ui layout more or less to pre- Mar 5, with some improvements. (Tim)
