It's nice that we can exclude SQL from the trend charts, but sometimes those excluded queries are actually the problem... it would be handy if we can toggle whether what is excluded is displayed or not.
If you look at the bottom of the trend charts, you should see a comment "There are SQL statements that may have been excluded from this chart. View excluded SQL" with a link to the excluded SQL which will let you de-select SQL from exclusion.
Maybe a toggle button on each excluded SQL statement could be added, but I'm not sure how useful that would be.
What I meant was something that would toggle whether all excluded items were excluded or shown at once. That would allow me to see at a glance if one was having a greater impact than anticipated; then I could choose to include it or not. Having to toggle each one to figure out if it's a problem child doesn't really help.
