Thanks for kind words.

BBR's innovations and changes, while untested by time and success, are more than cosmetic. Removing dust and the resulting bloat is a big step. Aliases are nice to have available. Two minute blocks may be a better choice than one minute. Wild Keccak may prove more ASIC resistant than Cryptonight. BBR was first with a GUI wallet as well.
......
I just want to mention, from my point of view most important, major core changes in BBR is:
1.
Advanced transaction identification --> precisely this option allow BBR to have n-times smaller recent blockchain compared to monery/bytecoin (assuming the same transactions amount)
2.
Transactions with guaranteed anonymity --> this option solve CryptoNote issue and will allow BBR to have subset of transactions with completely guaranteed unlinkability of transactions.
3. New different approach to PoW to solve problem of slow hash/slow synchronization and improve ASIC protection.
Removing dust, aliases, signed alerts - i could name it "minor changes" (but still it is not cosmetic as monero propagandists try to show it). Even each of this feature have concreate purpose (dust removed since it make smaller bc, alerts needed for fast notification in case of critical problems, aliases - for aliases, and basement for colored coins)
What i want to say - could be different view on solving these problems, different solutions - for example smooth mentioned that they aware about 2. problem and working on some different approach. And if they get better solution i would be happy to use it.
But calling these changes "cosmetic" shows complete misunderstanding of CryptoNote technology and ideas.
