Imagine you already wrote 5 different combinations on the same page. Color, thickness, pen style.

I'm thinking of a "picker" button on the left edge which I can press & hold with my finger. (enabling picker mode until I lift my finger)

When I tap the pen on the document, a zoomed hover-view shows up, I drag onto the pen stroke I want to reuse & lift off both my pen and finger.

Simple & useful.

But now when I want to write a title after a black simple text, I have to click red color, increase the thickness, change the pen style to brush. And after writing the title, I repeat the same process for the simple text. Black, thin, ball pen.
