Description of the new feature/enhancement

As bugs.kde.org/show_bug.cgi?id=485923 describes:

STEPS TO REPRODUCE

Invoke Konsole, and use a command like cat or github.com/MicrosoftDocs/PowerShell-Docs/blob/04dac6ae6b2abcb91006b6a515cc26c72219ffd5/reference/7.4/Microsoft.PowerShell.Management/Get-Content.md#example-2-limit-the-number-of-lines-get-content-returns to output the content of a file to the terminal.

OBSERVED RESULT

Without using cat's -b or -n flags, the content cannot be numbered. For others, like the aforecited Get-Content, it's impossible to output line numbers without writing code for every interaction to iterate over the lines.

Konsole has since gained the ability to display line numbers, as discuss.kde.org/t/14435#always-3 depicts:

It's been invaluable for me, when reading long logs via the terminal. Consequently, I propose the same for Windows Terminal.

Proposed technical implementation details (optional)

I'd rather that they be in a permanent separator following the text direction, or on the opposite of the text direction, still separated regardless (to prevent overlap). Specifically, as bugs.kde.org/show_bug.cgi?id=485970#c3 describes:

I want it to be like a Konsole/Dolphin panel, so that it can be moved to the left or right. However, I'd like it to work like a plasmoid on a PlasmaShell panel does - when a new session is invoked (like when a new tab or window is created) it should be static, and not overlay, like any other panel does. However, I should be able to set a toggle (like PlasmaShell's pin feature) and have it then able to temporarily resize over the session until I pin it again, where it returns to its original size. It should also have a horizontal scrollbar for when the user accidentally sets it shorter than they need at the start of a session.

Does that make sense?

I expected that this implementation wouldn't be possible due to wt's apparent lack of comparable "panel" support, but #997 (comment) demonstrates otherwise.

Why is less -N (or similar) insufficient for this/?

[RokeJulianLockhart]

#17490 (comment)

@zadjii-msft, because that's solely usable when piping command output. It doesn't operate retroactively. Additionally, if I run Get-ChildItem -LiteralPath "$HOME", I see coloured highlights for certain directories, whereas if I invoke Get-ChildItem -LiteralPath "$HOME" | less -N on Fedora 40, I don't (so it breaks command output).

Hey there! We found this while going back over our Attention backlog.

We don't currently have the architectural support for this (considering that the terminal's scrollback buffer somewhat dates back to the original Console one), and we're not likely to change that any time soon. Given that, I'm gonna close this request out. Thanks for writing it up, and giving all the grounding materials for it. We'll still keep it in mind for the future! 🙂
