Comment 7 for bug 1672139

In bug 469416 (Add "Folder" to the properties pane of bookmarks when viewing
search results), I attached a sample UI (attachment 392021 [details]) which includes the "View containing folder" button" proposed by this bug. It also includes
- "Folder column" for results table (bug 469421; SM bug 56418)

With respect to this bug, I have added the button right next to the folder widget which displays the name of the containing folder. Fits in nicely, imo.
Comments welcome. UI-review might be centralised in bug 469416, as the folder widget and button should go together.
