1. You have to be pvp flagged to see "PVP" there if you are not flagged there is no text.
2. I'll put it into my suggestion box.
3. It should show a green box in the topleft corner when a unit is buffed. You probably wrote the name wrong. Try only a part of the name like "Fortitude".
4. There is no gap. Here is how it works:
These areas are predefined and should work in most cases. Its so that the texts don't overlap. There is no way to tell how long a text is gonna be so having it dynamically adjust itself is not an option.
5. No. Its just a quick way to have an idea about your level progress.
6. Possible yes. Useful.. maybe. Will i spend time writing long explanation text for simple options to make even the last fool understand? No, definetly not.
