I think, you should have a specific gameplan and should be very sure, that they are an improvement, before you start shaking things up. POB works right now.

Right now the simple design and the high price are pulling a ton of people into POB. Changing the design and selling of thousands of POB at the same time, will risk both. It might work. It might not.

This is where I would start, because you can't do anything wrong with these things. They are straight up improvements, without the risk of changing a winning formula:

Notifications
Hive Wallet Management
Text Editor
Payout Info Popup when hovering including beneficiary info
Voting Power displayed prominently in wallet

For these things I would support hiring a developer and selling POB, if you must. I just want you to be aware of the risks.

I wouldn't tamper with the design until the community growth has slowed down a bit. Maybe in a few months.
