Indicate changes between snapshots

Color coded changes within a package in DEV stage:

A star indicating a change in the dev stage of a package is good, but in complex packages it might not be easy to spot what changes has been added (and not yet promoted/saved). Color coding unsaved changes would make this easier to see work in progress and collaboration in packages and deployment profiles.

It allows also to easily spot drag and drop changes by mistake.

Combined with a step back action to revert single changes this would be a killer feature
