Leader and multileader

Using Bricscad v15 on windows 10 pro.

Hi i'm quite new to Briscad. Not use how to use how the leader and mleader works.

For leader, when I draw I see 2 segments and 1 landing - I just want 1 segment and 1 landing - how to set this option?
When I skip the 2nd segment and draw 1 segment and 1 landing - the landing length cannot be adjusted - this make my leaders have all different angles - how to set angles for my segment line?
When I move the text, the leader follows, but when I move the leader, the text doesn't follow - how to make them move together?

For mleader, am I supposed to be able to draw my arrow leaders coming from one text? I just end up with one arrow and one leader - how to draw multiple leaders?
By the way, my mleader has 1 segment and 1 landing and the leader and text move together and the landing length is adjustable haha.

Confused now. No youtube video to help.

Thanks!
