00:17:511 (2) - could probably delete this note, it matches up with the rest of the section nicer as well
00:23:590 (1) could put this slider either a bit further away or tuck it under the 00:23:538 (3) , it just seems a bit awkward where it is right now
00:48:538 (1,2) - could make slider 2 point at 1 instead of away from it. more consistent with 01:08:748 (1,2) as well.
could replace 00:49:169 (1) with 2 circles instead and make it part of the stream, so instead of 00:49:169 (1,2,3,4,5,6,7) you have something like 01:09:380 (1,2,3,4,1,2,3,4) which i personally think looks more nice.
you could make 01:19:090 (2) the start of the stream and put the actual start of the stream 01:19:169 (1) a bit further away from it so the spacing between 01:19:090 (2,1) and 01:19:169 (1,2) is consistent
