mempool.space caters perfectly to people that just "arrived" at this world and are looking for ways to better understand their knowledge about mempool, transactions fees, current block mining, etc.
That's a good point but I'd argue that the newcomers should first choose a decent wallet and stick to that for fee estimation instead of using any third party webtool.It's very likely going to be improved in the next update. A new chart library is supposed to be implemented.
Music to my eyes ! Really looking forward to it, as long as it's functional the interface can stay the same
