Hi Milanis,
Thank you for your post.
We did used to have a dedicated Feedback/Feature Request site but this was closed in February ( The Future of Unity Feedback )
Honestly, the best thing to do right now is search for a thread in the first instance just to see if there is a thread already created with your idea and if not, make a thread in the most accurate subforum that it relates to.
While not every Unity employee posts here, they are actively read by a lot of people here. The feedback is most appreciated so please do this if you have any ideas to make Unity amazing.
