Vector and Raster Layers

Here you can see some expressions, which I now want to clean up with a thin outline.

For this, I will now create a vector layer. Conveniently, there are both vector and raster layers, and I will select the G-Pen from the pens here.

Sub Tool Detail Palette

Since my lines should look uniform here, I will go to the Sub Tool Detail Palette, then to Brush Size, click on this cheeky symbol here, and set the minimum and maximum values to the same size.

Stabilization

If you start cleaning up now, the lines might look like you've been shaking a bit. This is called pen jitter and isn't necessarily due to you, but rather the technical evolutionary stage of your tablet

But you can compensate for this by increasing the Stabilization value in the Tool Properties. And behold, no pen jitter.

 

Rotate Canvas

For beautiful continuous lines, you should always draw them in your direction.

To achieve this, you can rotate your canvas by holding down Shift and scrolling your mouse wheel up and down.

 

Overshoot and Trim Lines

Always draw the lines cleanly through and beyond other lines.

You can then trim these afterwards with the Vector Eraser preset.

Here you can also adjust the intensity of anti-aliasing and the efficiency of the eraser. For fine areas, you naturally use the smallest one.
