I don't think I've found amazing things recently. Things worth using and things better than the alternative and things that are promising to maybe one day be great, yes.

But I'll single out one little thing: dust. https://github.com/bootandy/dust

Dust is meant to give you an instant overview of which directories are using disk space without requiring sort or head. Dust will print a maximum of one 'Did not have permissions message'.

Dust will list a slightly-less-than-the-terminal-height number of the biggest subdirectories or files and will smartly recurse down the tree to find the larger ones. There is no need for a '-d' flag or a '-h' flag. The largest subdirectories will be colored.

It's like a killer combination of du and sort oneliners that actually shows me what I want to know: What's the big stuff in this dir.
