Consolidation is your weapon against entropy
Entropy is the tendency of systems to become chaotic over time.
Entropy is inevitable and it's part of everything, from thermodynamics, to your kitchen counter, to your app.
Sometimes it's important to take a step back and look at how much variation has been introduced into the product so you can simplify things and make them consistent.
Consistency and simplicity are good friends and are well appreciated by your users.
Your users will struggle less, having to form multiple mental models for similar functions.
When entropy shows its ugly head, hit it with the consolidation stick.
