The best thing about this software is that it's very easy to use, you don't need any specific training or experience in order to get things up for running! All of our team members are able to operate without having to ask someone else each time we have problems with certain features (for example).
It sometimes can be slow when loading new projects but not so much as other similar programs I've used before - maybe because ours has less users? Overall no complaints from me yet since all my previous jobs required more extensive knowledge than what necessary with Newtonx. We're now using Newtons tools at work during an ongoing project which involves lots of design documents created by many different designers across multiple teams / departments within one organization; they also help us manage client feedbacks etc..
