I don't mean other lessons/songs. I remember from your post in the past that the old lessons didn't have that. Hopefully they will get re-worked/upgraded.
I mean this particular lesson/song and probably many others by the look of it. It just looks like some parts are omitted and without them (indications of downstrokes/upstrokes). I don't get the reason/logic behind it. Almost the whole song is done but some chunks are left out/
I thought that it might be because of no space/not to clutter the notation too much or something but this doesn't seem to be the case since there are wide/open places without them too/
