They should rather fix useless built-in Mail client. Wanted to switch from Outlook over recent design changes, but that Mail built-in Vivaldi is even more unusable requiring you to use some left panel, which will cover the list of messages, you just can't have simple Mail client in one tab without some annoying panels.
