Note that in the online help, we have already some usages of level
speaking about frames.

So, all that taken into account, my preference would be to remove
the frame number wording,
and use frame level everywhere in the doc and online help : 
LEVEL seems more clear/intuitive than NUMBER or ID

But whatever choice is ok for me.
