It would be really useful to be able to toggle between Before and After for all of the adjustment tools with one button or keystroke, rather than just toggling them individually as at present.
Phocus is always several steps/years behind other software companies.
To be fair to Phocus, it is possible to access the adjustments history list in the pull-down menu from Adjustments in the top toolbar and at the top of the Embedded list should be the original Import version, which is effectively the Before version.
