'Unsorted' bookmarks

I would like to be able to rename the 'Other bookmarks' folder because it 
interferes with the keyboard shortcut for my other folder beginning with 'O'.

While we're at it, couldn't we have a possibility to choose a default folder 
for new bookmarks not placed into a specific folder?

By the way, why did anyone think 'unsorted bookmarks' needed to be renamed?
