# Description
Adds:
```nushell
$env.config.show_banner = "short"
```
This will display *only* the startup time. That was the only information
from the banner that the user couldn't possibly include in their own
config/banner (since it is `-1ns` during startup). This allows one to
create their own banner and yet still show the startup time.
Example (can be a file named `banner.nu` in autoloads:
```nushell
$env.config.show_banner = "short"
let ver = (version)
print $"(ansi blue_bold)Nushell Release:(ansi reset) ($ver.version) \(($ver.build_os)\)"
```
---
`true` and `false` settings continue to work as they do today. `true` is
still the default.
# User-Facing Changes
New configuration option:
```nushell
$env.config.show_banner = "short"
```

◼️ Update doc
◼️ Update `doc_config.nu`
# Description
Uses "normal" module `std/<submodule>/mod.nu` instead of renaming the
files (as requested in #13842).
# User-Facing Changes
No user-facing changes other than in `view files` results. Imports
remain the same after this PR.
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
Also manually confirmed that it does not interfere with nupm, since we
did have a conflict at one point (and it's not possible to test here).

### Nushell Startup - Load full standard library
Measures relative impact of a full `use std *`, which isn't recommended,
but worth tracking.
```nu
bench --pretty -n 200 { <path_to>/nu -c "use std *; exit" }
