Since there are many other apps supporting what I request, I think the text alone will be enough to communicate what this function this is.
Additionally, I will add what I want only for the Straight line.
If you keep the straight line in your Free Hand, I hope you will automatically switch to the Straight Line. Of course, this function should be on/off toggle.
The Straight line is available as an option or as a separate tool now,
but we must switch tools accordingly.
This is the user’s desire to immerse themselves in text and study without switching tools as much as possible.
