Not yet... But, We designed UMIT to don't make you wait the next UMIT version to use the latest stuffs released at nmap. It's not well documented yet, but I made a quick how to abou it.
This morning I checked my e-mail and wondered that Fyodor released an Informal version of nmap (3.96BETA1). He added some new stuffs to nmap, like --max_retries and --host_timeout. Certainly, these options are not present at the current UMIT's version. But we still can use it, and better: customize your interface as you like without knowing a shit about programming.
Take a look at the How To and try it yourself!
