The new format of Thingiverse seems nice, but it's really screwed up in one major respect. I have a lot of collections. When you find a Thing that you want on the main window and select 'save to collection' the drop-down selection box will only show 30 collections max - I have at least double that. If you select the Thing and try to 'collect thing' from its page, same thing: only 30 collections. I've only found one way to get to all of my collections, and that is to select the designer of the Thing, go to his/her page of designs, and the Things displayed there will have the old 'select a collection' drop-down that will show more (I assume all) of your collections. This is a big nuisance and an abject failure in web page design. I only hope that they don't 'upgrade' the designer page to a similar fail.
