For PowerShell language, one of code style can be formatted as:

Do-SomeFunction -Argument1 value1 `
 -Argument2 value2 `
 -Argument3 value3

Indentation for parameters is equal.

When typing a second line and put "Newline" character - cursor goes to indentation as at previous (second) line - and it is expected. But when typing a first-line and put "Newline" character - cursor calculates indentation as a previous first line (it has no indentation) - and after that user should put several additional "spaces" for making a correct indentation.

It will be cool if cursor calculates the first occurrence of argument and make the same (equal) indentation.
It should be done only if the latest character is "top comma" ( ` )
Maybe it should work only if indentations place by "spaces" but not tabs.
Maybe such new behaviour should be turned on/off by additional preference.

The feature request was previously created at the vs-code repo.
They mentioned that the current extension is a more preferable place.
