Please rewrite the browser, it seems very heavy, slow to load, and gets stuck; it is not smooth at all.  
On the other hand, the web [https://cosmos.chaos.com/](https://cosmos.chaos.com/) browser looks agile and fast, I run it on Chrome and it is quick and responsive.

Please rewrite it because it really makes using it a poor experience for the user.

This lack forces me to go to the materials from the old libraries of both V-Ray and Corona, which are much faster to use.
