Sort by multiple columns

Suggestion: enable a shift- or ctrl-click to sort by multiple columns.  For example, clicking on Name currently sorts by name.  A ctrl-click on the Year column heading would sort references secondarily by Year (so that all articles with first author of Einstein would be grouped together, but sorted by year).

The quick method would be nice, but you are aware you can sort now on multiple columns?  Tools>sort library. 

thanks leanne!  yes - the quicker method would make that feature actually usable.
