Indentation of wrapped text dependent of the sub-item’s “depth”

[plamkas]

I am working quite often with lists within Cherrytree and believe that using a similar approach for the indentation of the sub-items wrapped text (the subsequent lines) like word processors (MS Word, LibreOffice Writer, etc.) could improve the readability significantly. Currently, Cherrytree uses constant indentation for the wrapped text regardless of the list sub-item "depth" (link). This way it is more difficult to locate the sub-items quickly. Word processors use different indentation for each sub-item (link), thus making each sub-item stand out and appear like a separate text block. I my opinion this makes the list easier to read.

It would surely make sense, the problem is that I don't know how to achieve it with Gtk3 at the moment
