Feature request: Line operations

[PatrLind]

Describe the solution you'd like
I would like to have the possibility to do line operations. The most simple operation that I needed (but couldn't find) was to remove all empty lines of a text file.

Describe alternatives you've considered
Regex, but it gets complicated fast

Additional context
Notepad++ have a nice set of line operations that can be used for inspiration

I was looking for something like that last week too, I wanted to convert a multiline text into one line.

I would like to try and contribute to that.

Looking a bit deeper on this, there is indeed a operation called Remove whitespace that can be used to remove empty lines.

Oh, you are right! I didn't see that one, Thanks!
And sorry for the unnecessary feature request
