Currently, Okular shows a fixed amount of pages in one row when using Overview mode. Having to set the number of columns to a fixed value is limiting. As pointed out at https://askubuntu.com/questions/1098265/okular-set-arbitrary-pages-in-one-row-under-the-overview-mode zooming out, the pages will shrink in place. The number of pages in row stays same, with more padding between thumbmails. It would be nice to have an option (maybe even as another view mode), where the number of pages in one row tries to minimize the padding given zoom level.
