Maybe not the most useful idea ever, but.... maybe being able to choose what is deleted at system startup? as well as having certain set options when CCleaner is run with the context menu.
You can obviously select what is cleaned when CCleaner is running. But there are certain options that i just dont need at system startup. For one Empty of recycle bin.
It just generally comes down to for me is to try and speed it up a little bit more when windows loads.
