agreed, we should be able to drag/drop those popups to where suits us, as we do with the chat window.
related: why are the friend request popups on the same timer as colds/apt invites? if someone sends an FR, and I've walked away for a minute, then I miss it, and the sender may feel slighted. the pose invites stay centered until replied to, so why not friend requests as well?
sorry to add onto your query, @Fanny. just seemed an appropriate time to mention this as well.
