Sometimes one wants to open a few (but not all) bookmarks from a nested bookmark folder. It is tedious to navigate through all of their parent folders several times in a row.
It would be nice to be able to hold ctrl/cmd and click on a bookmark from the list, so that the bookmark opens but the popup with bookmarks is not closed. This way, one could click several times in a row without losing the context.
This feature exists in Chrome and works well.
