Disable a package completely

To completely disable a package and effectively uninstalling it even if it is part of your used layers, look for the variable dotspacemacs-excluded-packages in your dotfile and add the package name to it:

dotspacemacs-excluded-packages '(package1 package2 ...)

Disable a package only for a specific major-mode

This is done by removing the hook added by Spacemacs. For example to remove flycheck support in python buffers, look for the function dotspacemacs/config in your dotfile and add the following code:

(remove-hook 'python-mode-hook 'flycheck-mode)

Hint to know the name of the major-mode of the current buffer press: SPC h d v major-mode RET

Disable company for a specific major-mode

It may be handy to disable company for a given mode if you plan on configuring auto-complete instead. On easy way to do it is to use the macro spacemacs|disable-company in the function dotspacemacs/config of your dotfile. The following snippet disables company for python-mode:

(spacemacs|disable-company python-mode)

Change special buffer rules

To change the way spacemacs marks buffers as useless, you can customize spacemacs-useless-buffers-regexp which marks buffers matching the regexp as useless. The variable spacemacs-useful-buffers-regexp marks buffers matching the regexp as useful buffers. Both can be customized the same way.

Examples:

;; Only mark helm buffers as useless
(setq spacemacs-useless-buffers-regexp '("\\*helm\.\+\\*"))

;; Marking the *Messages* buffer as useful
(push "\\*Messages\\*" spacemacs-useful-buffers-regexp)

Enable navigation by visual lines

Add the following snippet to your dostpacemacs/config function:

;; Make evil-mode up/down operate in screen lines instead of logical lines		
(define-key evil-motion-state-map "j" 'evil-next-visual-line)		
(define-key evil-motion-state-map "k" 'evil-previous-visual-line)		
;; Also in visual mode		
(define-key evil-visual-state-map "j" 'evil-next-visual-line)		
(define-key evil-visual-state-map "k" 'evil-previous-visual-line)
