Very small and simple addon that will automatically align any chatframe on the right side of the screen to the right on startup.
There is a strange bug that I'm trying to figure out right now. It's kind of confusing, so here's an example.
You have Simple Chat turned on, so your combat log is on the right side of the screen.
The addon will align the text in your combat log to the right
You unlock your combat log and move it to the left side of the screen
The addon will align the text in your combat log to the left
You move the combat log BACK to the right side of the screen
This is where it gets weird. The addon WON'T automatically align the text back to the right. To fix this, right-click the Combat Log tab, and the text will re-align. However, if you left-click the tab, it will align to the left, no matter where it is on your screen. I don't know what's causing it, but I'm trying to figure it out.
