Roscosys – Please be clear what you want to edit. You can definitely edit the slugs just read this

and the core hack is not advisable – it means we dont advise editing the widget file as it will be overridden when you upgrade.
There are various widgets that i’d like to change.

– The Recent site wide posts widget i’d like all 5 recent posts to show an exert of text from their posts, currently it only shows the first posts exert.
– At the moment only 1 upcoming event is shown, i’d like to show the next 10 upcoming events.
I always draw up a ‘readmebeforeupgrading.txt’ file with the changes so come upgrade time, I remember what I’ve done
