It’s an alternative shell for Plasma, so theoretically you should be able to do anything in it that you can do in Plasma.

On my Arch box it installed a minimal set of Plasma utilities to support it, which means my setup is still very limited (and I can’t turn off screen lock!), but I haven’t tried if it would change if offered a full Plasma install.

I can most certainly launch Steam, Kodi, Jellyfin etc.

You can also do that in Tubular, if you prefer a FOSS option

It’s markdown, you should be able to indent your lines by 4 spaces or fence with triple backtics to get code blocks. Your client’s editor may have a button to help

```
$file = Get-Content -Path .\individuals2.txt

foreach ($line in $file)
{
    Copy-Item -Path .\template.docx -Destination ".\$(2 + $line + '.docs')"
}
```

Becomes

$file = Get-Content -Path .\individuals2.txt

foreach ($line in $file)
{
    Copy-Item -Path .\template.docx -Destination ".\$(2 + $line + '.docs')"
}
