Yoroi + Ledger ( + something new in the header?)

Hi all,
This is my first time posting on the forum and hope this is the right place to ask this question. I’m using a Ledger Nano S and preparing to move from Daedalus to Yoroi. Unless I’ve missed it all along I noticed just recently that next to the Yoroi and Ledger icon in the upper left side of the page header there is another icon along with the name of my wallet and an 8-character identifier. ####-####. Is that new?

Yes, the number plate is added to easily identify the right wallet when restoring or using multiple profiles. Check this for full description


Thank you for the quick reply and the detailed answer.
