One question...

Theme: Front panel

The section lines in scales had rounded ends in former versions. How can I achieve this?
Place a new scale and select it by clicking on it's handle cross. Then type key [e] for edit and select the lines on the left:

1 (Fig. 1: Change lines)

In dialog "Change Lines" you set a hook at "Rounded":

2 (Fig. 2: Rounded line ends)

Please regard that the checkbox "Rounded" has 3 states. You need to set a small hook.
