This library attempts to simplify removal of all frame (window) decorations as a global minor mode.
Install it from Melpa or clone and
install manually, then simply M-x decor-mode.
Automatical usage on start can be enabled in your config file with:
(use-package decor
:ensure t
:config (decor-mode))Alternatively you can use one of these public functions:
decor-toggle-single-frame(win-id on)decor-toggle-all-frames(on)decor-all-frames-on()decor-all-frames-off()
Documentation on those can be found via C-h f <name>.
