Electrum automatically creates new addresses so that you should always have 20 unused addresses available.
Isn't this the case for you?
Change addresses can't be moved to the normal addresses area.
They are from a different path of the BIP32 tree.
I don't know if it's working correctly.
The RECEIVING addresses are all used, they are 8 and they are all labeled, and under USED there's another one used and labeled, nothing else.
Addresses in CHANGE are 11 and 1 is labeled, and in USED under CHANGED are 14, one is labeled.
I can't understand the BIP32 tree: too technical, I don't know what it is.
However, for me no matter under what tree the addresses are generated: I, as a user, don't care about that.
I would like to organize them in folders in example, and I can't.
This wallet interface is made for CODERS, not for USERS.
Maybe it's time for Electrum for the next step and implement a decent, beautiful, comfortable UI?
Smartphone wallets are making steps forward in regards to user interface development.
