• [x] I have searched the existing issues

Description of the Issue

To improve readability, please provide a option to have alternate lines/rows with different background colors.

For e.g. one line would have a white background and the next a very light gray background.

Wonder why text editors haven't implemented this so far. Very useful if the notepad++ window is very wide.

Thanks for this great text editor.

Describe the solution you'd like.

See above, please provide a option to have alternate lines/rows with different background colors.
