I like that it's easy for me as developer, because you can use this tool without any difficulties or problems with code changes in my application after upgrading version of laraver from 5.* till now 7* which was released just couple days ago! It helps us not only by automatic update but also makes our life easier when we have some issues during migration process (which sometimes happens).
If there are no bugs - everything works perfectly fine :) And yes i'm using all features mentioned above so far nothing bad what comes into mind about shift feature yet :D All things go smoothly until date ;) Try out if your app supports migrations then definitely try!! We dont need manual work anymore while migrating database tables between different versions since its done automatically thanks god.
