Print and Print-preview scale handling

- it would be good to select and store the Print and Print-preview scales
in the Current Drawing Preferences panel ; and to avoid a spurious automatic-fill
when reopening a file, the latest entered print scale should be stored when closing the session.

- Is it on purpose or a minibug : when selecting a new Print-preview scale and clicking 'fixed'
LC opens the draft screen instead of the updated preview on its selected paper format.

Is it possible to get the scale presets
in a magnification continuum,
opening with 1:1 as default ?

(and  have the selected one
automatically printed
at the bottom-left corner
of the page)
