Thanks for the clarification. I understand your point but I think the actual fix here is more improving how minicron deals with lots of data. It shouldn't be a problem to have several months of data but I am aware it can slow down parts of the web ui down currently as it doesn't handle it well.

If pagination/limits are implemented in the relevant places I think this can be resolved without requiring the ability to delete old data. This is related to #238.
