The new tooltip on key held down is frikkin epic. 
Thanks for that.
When using the "generic files and folders" (sample) tooltip type, it's even filetype context aware.
Album art and everything! 
Although when hovering the mouse in the name box, but not over the text (whitespace) the tooltip won't trigger. Could you add a "full row tooltip trigger" please. So you could even be down to the right with your mouse, looking at the other columns and still use this, without having to have your mouse over the name text. pls pls 
And it still has like a 500ms delay, even when 0 delay is set in the settings.
Is that just the wait time for it to read the info?
...
If you gonna play the game right boy
You got to learn to play it right
You got to know when to hold em
Know when to fold em
Know when to walk away
And know when to run
