make better / BuffFrame:Hide();

[jlrm365]

I found a brilliant UI addon, but it still shows the auras / buffs in the top right corner.
I'm not a coder, but read through the LUA of a few addons and found:

"BuffFrame:Hide();"

I was able to make that work with /run BuffFrame:Hide();
It seemed smart to put it into an addon, so came up with:

function events:PLAYER_ENTERING_WORLD()
	BuffFrame:Hide();
end

It was put into the correct toc and lua configuration, so that wasn't the problem.
Simply changing the lua to just that one thing - to just "BuffFrame:Hide();" (no more lines or words) - made it work.

The thing is that I'm sure that can't be the slickest / most friendly to the game way to do it.
I'd simply like to hide that Buff frame utterly and always. What would be the simplest way to use "BuffFrame:Hide();" to do so?

Thanks!
