This addon is really useful. It also happens to be one of the addons with highest CPU usage, even surpassing WeakAuras sometimes.
Is there anything that can be done to reduce this (low-hanging fruit)? Perhaps the addon can be run with even an lower resource consumption when the map is closed, or when the player finds themselves in an instance (dungeon/raid/battleground/arena/delve)?

Excerpt after running a delve:

Will continue to use the addon nevertheless. Thanks for the already great work!
