Popwin automatically configures pupo purposes
if properly configured. While I was checking
the existing configs I have found that the
settings will be ignored if the config is not
done via a post-config hook.
A quick search revealed a lot of popwin configs
which never had any effect.
This commit fixes these and with this also
restores the missing pupo configs.
This layer was using two global bindings SPC a w and SPC a W.
As the available keybindings in that sub-menu are dwindling
I have moved the bindings to SPC a w w and SPC a w W instead.
This reverts commit 29c78ce841 and all other fixes
that have been made afterwards.
The motivation is that use-package is seen by many as a replacement for
`require`. Is use-package always defer the loading of packages then is breaks
this use case, this does not respect POLA so even if it was making Spacemacs
loading faster (up to 3s faster on some startup on my machine) we just cannot
use it, it would be irresponsible. Spacemacs should be easy to use, loading
performance will come with time but it is not a priority.
