want a lot of lime leaves?

One of the vertical leaders on the lime tree snapped under the weight of its three little limes, lost a good couple of feet. Shortsighted beast. I snipped the branch up and am seeing if any of it will want to root, but is there any use for the foliage? Bruise for room freshener? Use like kaffir lime leaves in cooking? They smell something like.

Hm, "If fresh kaffir lime leaves are not available, use the tender new leaves of lime, lemon or grapefruit. They won't have the same fragrance but are preferable to using dried kaffir lime leaves. Do not use kumquat leaves." -- "The leaves freeze well too."
