IMHO salesforce give you a interface where you can customize grids, I see people go crazy over it and I don't see what's so exciting,
its not like wix that the regular joe can setup from A-Z, you need to hire developers in order to make it work for you, and for developers they can set CRUD operations as well, so which problem set are they solving here.
and for you I guess it's a decision about your financial future to be a salesforce developer.
