not sure if this is just a misunderstanding or a feature request...
with "z" I can toggle selection and loupe cursor modes in the contact sheet
why not using selection as standard mode but whenever I click a SELECTED picture, the loupe is shown?
would basically make the "z" toggle superfluous
btw, can the loupe be configured in any way? size/orientation of source area and critical focus mask as in C1 would be nice
