I think this should be great to have a feed like for FB or twitter to know what are last change. Like by example :

10:15 Sarah just changed (Company Name) number

10:02 Justin just changed the status of (Opportunity name) opportunity into win

10:01 James just create a new opportunity for (company name)

etc etc...

We could choose for what field each user want to want to display in the feed...

Maybe this is already possible and I don't know ?

Maybe we need to create an app on creator to get this ?

Thanks for replying
