There should be a possibility to delete unused account or at least hide them from the main screen. A friend of mine requested 1 polish slot for a joke and now I have a polish slot account in between some other currencies that is just there and I cannot do anything about it.
My suggestion would be to be able to show/hide accounts from the main view. Or delete accounts that have a balance of 0.
Another thing I dont like is in that the account view under any foreign currency account name you show the balance of the account also in GBP (or at least thats what I have) this is very useful to be able to track the value of you account but why do you assume I want to see that in GBP. This option should be free to choose.
