Managing a large amount of message rules

I’m using the Rules and Alerts function extensively and I must have over a 100 rules by now to sort my incoming and outgoing emails.

For that amount of rules, the Rules Manager/Editor really is too small and cumbersome to use. For instance, there is no easy way to search or filter them and sorting/positioning them takes forever with pressing the Move Up/Move Down buttons repeatedly.

Am I pushing the limits of Outlook here? How many rules would you recommend and which alternatives do I have?
