...and not being able to label addresses makes Coin Control useless. When you have 30+ different addresses on the Coin Control list, it becomes annoying and very easy to mess up.
You can always create additional accounts in Ledger Live for different use cases. There are no limits to that as long as an address of 'account 1' was funded before you create 'account 2'. You can have an account just for your current signature campaign. If and when you switch to a new signature campaign, you can create a new account just for that one. You can make one for gambling, another one for trading. Or you can make one for each and every platform you use. Make one for family and friends independent from work and business activities. Mix it up every way you want. It's still not the same thing as labelling addresses, but is ok as a workaround.
