On the Transactions page, when filtered to a specific account, clicking on the "Add to Cash" button will create a new entry in the table, with the Account name auto-filled.

If the screen width is smaller, clicking on "Add transaction" will open the 'Add new transaction' panel, but the 'Paid from' field is set to 'Cash transaction'. Instead, it should behave the same as the in-line entry and have the 'Paid from' field auto-filled based on the Account being viewed.
