One thing I learnt going from frontend development, to distributed system database, development, and then back:

These neanderthal grade tools have the same problem: attempting to abstract away unabstractible problems. The MO of said tools are to limit expressiveness rather than provide context or knowledge.

Take the multi-tab syncing you mentioned. Syncing will always take a loop and a buffer, assuming a channel of communication is not a problem. Those can be in a library, in a browser's built-in API, abstracted away, or you can write it by yourself. But when you don't write it, you don't have control over it (e.g. when to sync, how to interlace the syncing with other operations).

A better toolings work in the level of paradigm. Instead of simply abstracting, bring complexity to clarity and provide the learning ramp.
