Combining best parts of all three OBS Default themes with a small tweaks here and there.
Install at Obs main folder/Themes next to the default ones, this re-uses some graphical assets from the default dark theme, so it needs to be next to the default themes.
1. Unzip at default theme folder: C:\Program Files (x86)\obs-studio\data\obs-studio\themes
2. Go to settings -> General -> theme, select night as your theme
3. Press OK
Version 1.0 tested to be working with OBS 26.1.0, propably will work later versions too.
Older versions of OBS may work, or have some problems.
I'm Posting this in hopes someone else finds use for it.
