I'm trying to have a list as
This is important because
\item[a)] \quad this,
\item[b)] \quad this other and,
\item[c)] \quad obviously this.
But all the packages that I have seen manages the indent space before the item, and I'm looking for an indent after the item. I could use '\quad' but it doesn't work if the text has more than one line. If someone could say me what is the package or code that I need I would be very grateful. I will appreciate any help or advice. Thanks.
