Not sure if this is the right place to post a feature request. But i`ve use 3d coat over the years as well as substance painter.
And one thing that has always bugged me (excuse pun!) is there isnt a search feature for materials and the like. I have probably 300+ smart materials. There isnt a way to list them, only thumbnail views. You have to hover your mouse, wait a second and then the name appears. Try that when you have 20+ folders of materials each container 30+ materials. Its painful.
Surely its time to have a search feature so you could just type eg. con ... and concretes would appear. Same goes for alpha brushes. This is such a useful feature in substance painter.
*Please* add a search feature.
