If you like oh-my-posh, you can use oh-my-posh with Nushell with a few steps. It works great with Nushell. How to setup oh-my-posh with Nushell:

Install Oh My Posh and download oh-my-posh's themes following guide.
Download and install a nerd font.
Set the PROMPT_COMMAND in ~/.config/nushell/config.nu, change M365Princess.omp.json to whatever you like Themes demo.

> let-env PROMPT_COMMAND = { oh-my-posh --config ~/.poshthemes/M365Princess.omp.json }

Follow the links above and install starship.
Install nerdfonts depending on your preferences.
Set the starship shell environment variable to nu by running this commend let-env STARSHIP_SHELL = "nu"
If you want the default ticking clock with date & time on the right prompt execut this command hide PROMPT_COMMAND_RIGHT
If you don't want the default indicator, you can run this command let-env PROMPT_INDICATOR = " "
Set starship as your left prompt with this command let-env PROMPT_COMMAND = { starship prompt --cmd-duration $env.CMD_DURATION_MS --status $env.LAST_EXIT_CODE | str trim }. Note that you may not have to use str trim in the Nushell prompt if you disable starship's default newline setting with this entry in the starship.toml file add_newline = false. There have been reports that this might not play nice with Nushell prompts. We're still testing.
Since Nushell supports a right prompt you can also play around with starship's ability to set a right prompt. Setting the right prompt in Nushell is identical to setting the left prompt however you use PROMPT_COMMAND_RIGHT.
