This is more of a UI/Docs wish.

In the L[og], UpArrow popup, I never know if the drive space stats are displayed as
Free/Total or Used/Total. I need to stop and analyze, compare, etc., to conclude what
is being shown. I actually go to the / display and look at the Capacity, Available,
Used Space to figure this out. Anybody else?

Different programs use different orders, some even show Free/Used/Total, but having
a clear info in the header seems useful to me. It's like a column name in Excel.

In ZTree, the first line that starts with "Fixed" is not used other than for these
5 letters, so there is plenty of space on the right for a header like "Free/Total" or
"Used/Total", whatever the case, that would solve the mystery for me.
