A Few (Hopefully Simple) Questions - ELA

I've been using the demo version of ELA for a few weeks now. I'm impressed with the product I will say. I am having some trouble though taming the powerful beast

Here are my questions:

1) Is there a way to filter out only specific event IDs along with a keyword? For example, I'd like to filter out all kerberos events on our DCs. (ID=672, 673, 676, etc.)

2) Is there a way to create or edit reports under the "Ask Me" section? For example, add "events in the last hour" to "time-based events.

3) What is the best-practice solution to maintaining our database? I've noticed that performance slows down considerably after a week or so. If there is a setting to ensure that our database remains a manageable size, I'm interested.

Thanks again for your help and a great product.

Dave
