It is great that you have passion for Polkadot and that you are actively exploring how to make staking a more decentralised system, I can see this dedication unquestionably.
What I would suggest though is to refrain from using language like “its really bad” or “works awful”; these are very strong statements that will likely upset or at the least demotivate those who have actively been working on the dashboard and staking system.
We dedicate many many hours of our lives to try to improve Polkadot - and even though not all the decisions made along the way will turn out to be the best ones - rest assured that we all share the same enthusiasm as yourself and are open to improving decentralisation and fairness in the systems we create - this is after all the main reason we do what we do.
