UI feedback if an object has been saved or not...

I’d like to indicate to a user whether or not the object he/she is working on has been saved already (eg. greying the save button when there is no change). Any idea of how to approach this

Community commons has a function to check if an object has changed https://docs.mendix.com/appstore/modules/community-commons-function-library

For newly created objects (not committed yet) there is also the isNew function from Mendix.
It is not a complete solution it is a starting point
Hope it helps
