Q : what kind of projects can be done with the $99 licence? 

A : I believe the $99 license with 500 widgets, covers most projects. Also, the shape and image widgets don't count. If you open one of your projects in Comfile Studio, check the top-right corner of the Comfile Studio window, and you'll see the current widget count.

Q : How does additional licensing work in case of extra widgets? So can someone buy 3x $99 licences for one project with 1500 widgets? 

A : You can only plug one dongle into a PC, so if you want more widgets, you need to buy a dongle that supports more widgets.

Q :  Is this a hardware dongle or software licence?

A : The dongle is a hardware USB device that must be plugged into the machine that running the project.  The dongle has the license and widget quota burned in.
