/* TODO review todo notes
navigation (back, next etc) of tracks while a sequence is playing is flat out broken
if shuffleBy( "folder" ) && queue created; option to finish the folder first, play the queue then come back to the folder, or simply move on
include image files (which might be cover art, but could also be dick-pics) in uploads and display
sequencify folders for isShuffleBy( "folder" ) i.e. disc 1 & 2 of double album
temporary ignorables during not shuffled play e.g. skip tracks this time
break at marker?
disable marking queued tracks as played during otherwise shuffled play
repeat track, folder, sequence, queue (or playlist when implemented)
queue stuff to follow the folder playing during shuffle by folder
remake "played after" functionality using percentage played
start shuffle play again after e.g. finishing a folder etc.
select specific album to play during shuffle by folder
skip sequence button (instead of next next next...)
mark folders to be ignored during shuffle by folder
without being marked as played
mark newly added tracks and make them easy to find
mark tracks/folders to "never mark as played"
mark track to stop at; when queued and ????
display GLOBAL.played most recent at top?
gapless playback (surprisingly shitty)
show recently added button; filter?
prioritise UX for visually impaired
playing played sequenced tracks...
