I like how easy it is to create a documentation for each part of my project. GDOC works as an interface between an Electronic Design Automation (EDA) software and me. It is also available to the end user to use directly. For example, if you are working on a simulation model for your circuit board design, you can use this to prepare some screenshots that would be shown to the end users when they use the software. Creating and maintaining the documentation is easy using the tool and there is no need to pay for additional services. There's nothing really bad about this program. The only thing that bothers me sometimes is the fact that sometimes it doesn't update its internal system properly. Usually after working a couple of days it updates itself but not all the time. This makes it difficult to see which parts have already been updated. It helps me track what I've done so far and which.
