However, something about it might be improved, maybe the overall smoothness of it, because there are sometimes when I try to run a lot of applications, it tries to hang up on me.

There are areas for improvement in Kali Linux, particularly regarding its use of the Linux kernel, which requires external additional patching, and the fact that network services are disabled by default, which complicates usage; enhancing user-friendliness through more GUI-based tools and better integration could be beneficial.
