Hi guys need some help and its easy for most of users

(Please ask one question per thread)

For 1) Custom View toggle is a recent thread on the same topic.

For 2) The menus off the location bar are, as in Explorer, just to pick a sibling folder and not to give a full folder tree. If you want to do a deep navigation, it's less fiddly to do it in the main tree or file display rather than multiple nested menus opening off each other.
