As you may know, Ubuntu 16.04 LTS, code named Xenial Xerus will be the next big Ubuntu release, a lot of changes being scheduled for it.

Among the changes, there will be a brand new tool for writing ISO images to USB disks, the good old Startup Creator being completely redesigned. While the software has been ignored a lot lately, the developers are porting it to QML, in order to make it easier for them to maintain and update it.
The new USB Startup Creator will be capable of writing a variety of Linux images, not only Ubuntu and Ubuntu-based ones. While the terminal geeks already have a bunch of interesting tools to place ISOs to USBs, the new tool will be ideal for those who prefer applications with GUI.
