Since the newest update, the straightening of the highlighting tool has been "improved", i.e. when highlighting and holding at the end of the line, the shape resembles the original handwriting with more details. But that brings a rather glaring downside: when marking, one usually does not highlight in a perfectly straight line but rather with multiple bumps etc. When holding now, the highlighter often is not converted into a straight line through the text but rather a bumpy line with multiple edges and curves. It therefore does not go straight through the text anymore.

It would be lovely, if GoodNotes would make it so that the adjusted form of the highlighter would resemble the straight line more often, even if the handwriting contained some imperfections.
