I would like a change in the pm tabs. Now that i have 2 heroes, I sometimes have 4 tabs open with the same person, if they have a 2nd hero too. This takes a lot of space above the chat panel and conversations are often divided over the pms.
If you have a big army, you are not able to see the little triangle blinking, to inform you that you received another pm, because the army panel is blocking the little triangle.
therefore I would like to suggest, that not hero names are used for pms, but gen tags.
