The raid party window doesn’t save being in horizontal mode between parties. I’ve never cared to use horizontal mode before as I liked the party windows as the default vertical. However when the raid party contains more than 8 members (a.k.a. consists of more than 2 parties) I do not like the raid window being vertical. It becomes too big and can’t be placed anywhere that isn’t covering vital screen space.
It is in Rowen that I noticed this issue, as it is a common occurrence for faction members to create raid parties to keep track of allies on the map as the game doesn’t do it for you unless you are in a specific co-op siege event. And the only place that feels good to place the raid window is on the bottom right where it only covers menu buttons that one could still access with Esc anyway and doesn’t cover the center of the screen. So it would be nice if this gets fixed.
