While working with the new custom events, I've found a frequent pattern is to receive an event, check if certain fields match the thing receiving them, and proceed only if they do. Wouldn't it be awesome if unwired fields of an event receiver simply did this automatically? For example, if I were to set the third input of an event receiver to "abc" but not wire it to anything, the exec field would only pulse for instances of the event whose third input is "abc". Perhaps this is a bit too confusing and/or niche, but it's been on my mind following several hours of doing this manually.
