Clamping won't change as it is Blizzard's design that the tabs don't belong to the chat frames.
For the not-maximizing-thing:
If you got alts, profile them. If every character uses the same profile, then sometimes the following happens:
- Char1 has the chat window minimized as you log out. (default profile says: window is minimized)
- You play with Char2 which has it's chat window maximized as you log out (default profile says: window is maximized)
- Char1 logs on again. The window is minimized, but MiniChat sets this height as the height to use while maximized, because the default profile said so.
Another problem occurs if you log out during an animated minimization. While doing so the window is still maximized for MiniChat, but the maximized height is set to the current height during this process.
So once again: Profile your chars.
I hope that helps.
The build in fade triggers after some set amount of time and fades text to alpha value 0. MiniChat fades to a user defined alpha value, affects the whole chat window and is triggered by minimizing instead of after some time. You can set the alpha for the maximized window state, too.
I set it up to minimize to the bottom and the next time i relog, the bottom position becomes the top of my chat
Are you using the latest version? I fixed this a while ago, but if you are experiencing this with the current release I'll have to look into it again.
