Maybe a little off-topic but I wanted to share a tip to better control the frame start.
I had an unjustified obsession to get Emacs to start half screen to the left. I found a package moom that has a decent amount of frame magic.
After adding (package! moom) to ~/.doom.d/packages.el.
Run doom sync.
It allowed me to start half screen left with this hack at the bottom of ~/.doom.d/config.el:
(when (display-graphic-p) ; To not break cli-things like `doom doctor`
(moom-mode 1)
(moom-fill-left))
