Feature Request: Snap-to-Grid / Straight Line Tool for Pencil and Highlighter

I would like to request a feature for Notewise that allows users to draw perfectly horizontal lines 180° alignment when using both the pencil and highlighter tools.

Currently, it is difficult to highlight or underline notes without the lines becoming slightly tilted. While the lines themselves are straight, maintaining a perfectly horizontal orientation is inconsistent. Me and my friends have encountered the same issue and agree that a "snap" or "straighten" function would significantly improve the neatness of handwritten notes.

Implementing a long-press gesture or a dedicated toggle to lock the stroke angle to the horizontal axis would resolve this
