come on guys, this shouldn't be a problem to solve, give an option to set all bookmarks to "list view". i have like 500 folders imported from chrome, entering each folder to see a picture is very annoying, "list view" is what i like, but i hate to go in each folder to click it in order to find it next time there

any extension for this? if the developers are not capable to offer it

sry...I had experimental flag enabled, so I couldn't move bookmarks in Opera native bookmarks manager
that's why I recommended extension

Why can't you multi select your folders and move them?

box-selection (click with mouse in one corner and draw a box)
or selecting each folder with check box
