Save editor settings/preferences


Perhaps I am missing something?
I would like to be able to save settings/preferences for opening an integrated editor.

For example for Potlatch:

  1. do not show welcome dialog
  2. choice of background images and map style
  3. force map scale (zoom) and position on opening
  4. button settings: do not dim, show mouse latitude/longitude…
  5. toolbox: always show all tools (“show more”)…
    etc etc.

This could be in a cookie or as parametres in the URL.
Is it not possible?
Thanks, regards
