Admin>Content: Sticky Filter? + Add Colums to Content List

Hey,
There are 200+ pieces of content in my Admin/Content page.

I use the filter to find groups of information – which narrows the 200 to say 25.

I edit one item and hit save.

The filter resets and I have to set the filter again.

I went looking for a module – but could not find what I was looking for.

Question 1: Is there a way to “hold” the filtered state – so when I save a content item it returns back to the filtered state?

Also…

In Admin>Content – the columns appear as Title, Content Type, Author, Status, Updated, and Operations

Question 2: Is there a way to ADD a column to those columns – for example add a column for a DB#? (This stems from the fact some titles are duplicates and I need another way to differentiate them)

Thanks!
