+ Remove doom/switch-theme (replaced with an advice for load-theme) + Reorganize core-ui + Fix Emacs 26+ hl-line hack being applied for Emacs 25 users + Rename doom|show-whitespace-maybe to doom|highlight-non-default-indentation + Disable tool-bar, menu-bar and vertical-scroll-bars via default-frame-alist; this is a little faster than using the minor modes.

A real buffer is a useful buffer; a first class citizen in Doom. Real ones

them. Unreal ones should be low-profile and easy to cast aside, so we can focus

on real ones.

1. A non-nil value for the buffer-local value of the `doom-real-buffer-p'
|
|
variable OR
|

2. Any function in `doom-real-buffer-functions' returns non-nil OR

non-nil.
