Add a quantity option on the drop-down box for +Collection.

Thanks for the feedback.  For now, we are keeping the "+collection" option with just one click. If you want to add details like quantity, cost, photo, description, folder, etc.  You should click "+with details".  If you ctrl+click on PC or long click on a phone and select "open in a new" tab, you can add the full details and then close the tab and be on the same spot on the page if you want to add other items to the collection too.

If this is popular enough request we can look into adding a feature like this.
