One great-great-great feature in Ubuntu Mate is "Welcome"

 - Yeap in Linux, is all about getting the best software for your PC - and Welcome it does just that = it recommends the best apps for a variety of tasks

  - Best of all is easy to find, is always in your Menu < System < Welcome

 -  It looks great

  - Easy to browse

My personal thought =  Best app ever of its kind as far as i remember
( it resembles to the first page of Ubuntu Software Center, but is much better, because of it s simplicity... )
