A feature that I really miss from GR is the ability to create an ordered list. For example, I have been a part of a book club for the past few years, and I have a list (I suppose technically it's a tag) that I maintain of all of the books that we have read in the order that we read them. There does not seem to be a comparable way to do something like this on SG. Another example is that I tried to curate a list of 30 books that I wanted to read in the second half of this year. I used a Challenge to get around this, but it was rather clunky and ends up requiring a lot of scrolling to see what is next due to the bulk of Challenge entries (which make sense when they are being used as designed, but less sense when they are literally just a container for a title of a book).
