The free, offline Chrome app is a limited version of Gliffy Online, therefore it does not have as many features or capabilities. Gliffy will not be doing any updates, bug fixes, or feature improvements to the Chrome app in the near future.
If you are looking for a more robust application that we are doing updates to, we would recommend Gliffy Online: https://www.gliffy.com/products/online/
If you do not have a Gliffy Online account, you can start a free trial by going www.gliffy.com and clicking on the "Start Drawing " button. Once you create and attempt to save a diagram it will prompt you to enter your email and setup a password. Your free trial acts like a Gliffy "Business" account and gives you the ability to make unlimited private diagrams during that time. When your trial expires, your account reverts to a free, Basic account if you choose not to upgrade to a paid account. All of your diagrams will remain accessible and editable but you will not be able to add any new diagrams over a total of five.
