+** IVY-POSFRAME
+Ivy-posframe is an ivy extension, which lets ivy use posframe to show its candidate menu.  Some of the settings below involve:
++ ivy-posframe-display-functions-alist -- sets the display position for specific programs
++ ivy-posframe-height-alist -- sets the height of the list displayed for specific programs
+
+Available functions (positions) for 'ivy-posframe-display-functions-alist'
++ ivy-posframe-display-at-frame-center
++ ivy-posframe-display-at-window-center
++ ivy-posframe-display-at-frame-bottom-left
++ ivy-posframe-display-at-window-bottom-left
++ ivy-posframe-display-at-frame-bottom-window-center
++ ivy-posframe-display-at-point
++ ivy-posframe-display-at-frame-top-center
+
+=NOTE:= If the setting for 'ivy-posframe-display' is set to 'nil' (false), anything that is set to 'ivy-display-function-fallback' will just default to their normal position in Doom Emacs (usually a bottom split).  However, if this is set to 't' (true), then the fallback position will be centered in the window.
