The current Konsole GUI (with an example).

SUMMARY
I'd like line numbers.

STEPS TO REPRODUCE
Invoke Konsole, and use a command like https://github.com/coreutils/coreutils/blob/225cb8d7473eadb481a4884e929bf23589d4bd82/src/cat.c#L1 or https://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.

EXPECTED RESULT
I should have line numbers in the terminal, to its side (according to LTR/RTL preference).
