I totally agree! I still, after a year, go to the account screen to make a payment, and then back to the homescreen to find the pay button there... It has happened more than once that I accidentally used the wrong account. (Although that has been improved in one off the latest updates, where you can see and change the account in the first payment screen).
An yes, the 'Storting' (deposit?) button feels strange for a bank account. It's only use is to start using bunq, but now (I have about 10 accounts and use only bunq) it's a bit useless.
