The upper limit for m would be the total number of pages in non-continuous mode, e.g. 1 for a single page document. This mode would basically correspond to the behaviour you get when zooming the thumbnails in "Adobe Reader" or "Foxit Reader".

  Ok. Yet, I'm still new to QT, but I'll try to implement that. If I correctly understand you, you want the whole pages to be as small as possible, when you scale down the document and all of them could be visible in the viewport.
  
  Do all agree to remove the "checkbox" for the automatic reduction of columns? Or it should be user-configurable? Or I just should enable it by default (okular.kcfg:138)
