 ## Roadmap
+* add support for choosing a nsf file from a different drive letter (windows only)
 * add selective mute, so that you mute every music except the boss music, or every song except menu music or both.
 * figure out the best way to add a setting for changing each of the level editor songs, menu music, or a specific level song. Maybe an extra popup window or a check box for "replace every one" "menu" and "levelBuild"
+* add a way to change boss music separate from level music and menu music
 * add a way to show the available nsf files in the selected folder, like a playlist.
 * add a settings file for the last folder chosen, so if there is a path try to use that so that you don't have to choose it manually
 * fix slowdown on windows systems
