If the selected folder name is too long, the text of the folder name covers the menu icon making it unselectable. There is a work around of going to the website, changing the folder name, and repeatedly waiting and refreshing until the app syncs the change. Just letting you know, because it isn't the ideal user experience. I wish I could work at Toodledo, because you have a nice long backlog of items, so I would never get bored.
