Any way to remove the indents from tab trees?

[ItwasamiiDio]

I've been using the Auto-show/hide sidebar by mouseover (hover) code snipet from this section of the Wiki https://github.com/piroor/treestyletab/wiki/Code-snippets-for-custom-style-rules. It's great, but I'd like to remove the indent whenever I make a tree.

Is there something I can do? I've been experimenting with more code snipets from the Wiki but none seem to do the job.

Just change the base indent from 12 to 0.
