Designer > Layers Panel > Groups: No fillings for better indents/cognitive load

[gbrampage]

Maybe i'm missing something but what's the reasoning for these fillings?
It makes the whole panel seem more cluttered and adds cognitive load.

The lines more clearly show the indentation level, and with the lines showing you can click on them to hide everything at that level. That would be harder to do with your proposed "no fill" approach, in my opinion.

Indicating hierarchy with vertical lines is a fairly standard way to express and control (see Walt's note) indentation in complex hierarchical structures - thanks for implementing them. Unfortunately, Serif used the least clear and comprehensible variant.
This is how it is handled, for example, in a development environment to indicate a hierarchy in a program code.
