History navigation has disappeared in Yosemite

OS X version: 10.10
TotalFinder version: 1.6.16

Fairly sure this it not TotalFinder’s fault, but when upgrading to Yosemite, I lost historical navigation in my toolbar:

This can be fixed by going to View > Customize Toolbar… > drag icons back onto toolbar.

Apologies if this is outside the remit of the TotalFinder forums, but I thought this might help others who thought this was a display bug.
