If you assign scala-outline-popup command a hotkey (ex., C-e), you may wan't same key to close the popup. This can be done by adding the key to popup-isearch-keymap:

(require 'popup)

(define-key popup-isearch-keymap (kbd "C-e") 'popup-isearch-cancel)

Variable controls popup horizontal positioning. Possible values are:

• 'center - opens popup at window center
• 'fill-column - center relative to fill-column (default setting)
• 'point - open popup at point

(setq scala-outline-popup-position 'point)

It's possible to have closest, previous or next definition selected, when you open the popup.

(setq scala-outline-popup-select 'closest) // 'next or 'prev

Fuzzy matching is enabled by default. Set (setq scala-outline-popup-use-flx nil) to disable it.
