I like how it can be used to create an entire campaign from start to finish or even just one piece of communication material such as business cards, letterhead etc.
It's not easy for someone that has no graphic designing skills at all since everything looks very complex which makes creating something simple quite hard sometimes compared to other software out there in this market. However if you are willing to learn then pentragem could work well with your skill set but make sure to have some basic knowledge about what exactly each icon represents so that when needed they will come handy. Creating designs for our marketing department using pentagram allowed us to present them professionally while saving time by having their own graphics done rather than doing it manually ourselves.
