It would be nice if we could right click on a bookmark on the "Personal Toolbar Folder" and choose where we want to open like history does
You should be able to change what middle click and right click do with the prefs:
Strings with the command to use (ID_OPEN_LINK_IN_NEW_TAB, ... )
Dorian when Editing Bookmarks only to two options to open bookmarks which are "Open in Current Browser Window" and "Open in Background"
Some opening methods for right clocking in kmeleon.plugins.bookmarks are not displayed eventhough thrree mehtods for opening bookmarks is present in browser preferencess.
