Yea, auto-accept level could be risky to add, but auto-accept summon would be nice.

To be honest though, I don't know how you could implement summoning friends. There are to many parameters for how people summon, for example I abuse it hard. I have all 3 RAFs bound in home cities, and my main summons them, but they summon him - so in essence I have like 4 hearths, and can get my group together to any city in a flash. However it requires zoning once, then summoning my RAFs. I dunno I will keep mulling it over, maybe you can think of something to do with these functions:
There are two useful functions I know of:
CanSummonFriend()
SummonFriend()

I could see a timer of sorts (I think the friends list has a timer though, at least a button to push to do this) and a auto-accept being pretty useful.

The leveling macros are probably better suited as is, macros.

But things I know would be helpful:
Auto-Accept BG (Would probably need a time to wait before accepting)
Auto-Leave BG (" ")
Auto-Release (Would only want this in BG, personally - and not on shamans!)
Auto-Accept Summons (If you didn't want to summon, you probably should have moved in the time it takes to cast the summon)

Thoughts?
