I have never watched any of the video's I think at the time I owned a scrap rack they did not have any.
( I used two bases on a 6' table and it was the only thing on it) so, I decided it was too much of a space hog and I did get rid of mine a long time ago because of that, but I was really impressed with the workmanship of it, it was a quality organizer)
as far as digital organizing goes I have an evernote project underway. and because, I have been collecting tools for a really long time its going to be one of those never finished things. (because, I keep shopping) and I have never tried any of the others you mentioned. but, if you do a search in this forum for Scraprack or evernote you should find old threads with tips and chatter.
hth,
