Inkscape beginners tutorial - Bezier Curves & Freehand Tool - Mastering Nodes and the Pen Tool

Hi👋🏻🤲.My there is a question.I already have the bezier tool taking different forms, for example, when I draw a straight line, sometimes it doesn't change the width, I can't zoom in or out, then after I finish the line, sometimes it becomes invisible, it can't be restored, sometimes after I finish drawing a thin line, the line suddenly grows.I can send a video, I could explain it to you more easily.

Awesome man, keep them coming.
