Very helpful

I use it to create the table of contents for my posts.
I place it in the sidebar, and the indents provided by the plugin’s css are too large.
I resolved it by adding the following code at the end of the main css of my theme:

ul.toc_widget_list {
    padding-left: 10px;
}
.toc_widget_list ul {
    padding-left: 10px;
}
