Have I checked similar ideas? - Yes, nothing similar found. The reason: There is auto-collect for 5 diamonds in PC version. But the phone, which is much more approachable today, don't have this feature. The Idea: Add Auto-Collect button in Phone App (for 5 diamonds) * There is a reason why this feature costs 5 diamonds, so it's should be across all platforms. And, it's not something hard to implement.
