Delete column in email listing

I’m trying out your application and finding it quite great, tending to purchase the long-life pro version. BUT as I’m coming from Windows Mail app, there are just two icons at the email in listing. Basket and Flag. You offer the flag, but I miss the basket which is placed far in the email header toolbar. This is not ergonomic at all! Would you please add the basket as an option to be added in the email listing as another column, please?
