Hey Tyler, how are you doing, man?
I really liked the suggestions and I'll strive to implement them all by the next update. All your suggestions are interesting and will greatly enhance the tool. I hadn't even noticed the problem with the walls becoming invisible; I'll try to reproduce that behavior here to see if it's a global issue or a specific texture or condition.
Thank you so much for the suggestions. In a few days I'll bring updates to provide the best possible experience (Melee weapons were already under development).
Thank you for all the support and contribution!
