Didn't know what the new thumb was either, did a search and found this thread, I think its over engineering something that already exists, there's a just a click, that said I do believe in having a choice where possible, if the new thumb is here to stay can there be a down thumb as well?
On FB you can see who gave you a "like" and what type as well, but do we want to go that far, maybe not.
Not having a pop at the mods or Karlos, it must be hard to keep control of this forum, well done, just airing my thoughts
