Both suggestions are for convenience and luxury.
I’d like to suggest a feature to be added to the party window. Although there are means to knowing where the party is, an ability to right click on the party member/leader and select an option to change to their channel would be a helpful addition to the party list options.
My other suggestion is to allow automatically switching to the party leader’s channel when entering the map they occupy as a toggle-able system option.
Sorry if the second suggestion is already implemented. Just thought of it and the beta is already over.
