featureS requestS: "auto-toggle" depending on app and "hotkey combination"

[pickybl2020]

when there are a lot of windows/tabs open (e.g. chrome, gedit, xmind, vlc open at the same time) and you change focus/use a lot between them while using a keyboard, it's a lot more efficient, productivity-wise,

• to be able to have a keyboard combination as well
• or/and the option to custom auto-set to day/night light for apps of the user's choice
  -e.g. when opening/focusing on vlc to watch a video to auto-set on "day mode" and when i focus again to gedit/chrome/firefox or
  anything text related (set by user) to auto-set to "night mode"
