On the purchases page, it would be useful to be able to 'sort' this page by expense categories, If for example, I wanted to see the purchases I'd made that related to 'motor expenses' or 'stationary' or 'subcontracters' - the only way to do this is to look down the list and find them / hope I recognise them. It would be good to have different column options so you could sort the columns more easily too.
