Good article. I totally agree with that we are focusing too much of our efforts on our software skills. We use prototyping tool to help us solve problems and make our work easier. We need a tool which is going to enable us to quickly and easily create a prototype. Even though Dozens of prototyping tool are now available, it is difficult to choose the right one. I recently found a new UX/UI wireframing tool mockpls.com. This tool seems interesting. I can master it in a short period of time. It makes me totally focus on the design instead of spending time on learning the design tools.
