Searching for phone numbers

I hadn't noticed the Find / Filter feature! I'm very happy to have it. I'm still hoping that Search gets substring functionality back, too. But this is very useful, thank you.

From a discoverability perspective -
* I didn't know Find existed
* There's no GUI button to activate Find
* The behaviors of Search and Find aren't obvious
* The distinction between Search and Find isn't obvious
* The verb "Find" doesn't imply "Filter" to me

Find covers up other parts of the UI -
* When Find is active, Sort options aren't accessible
* After performing a Search --> Show all matching items -
* Find hides the 2 results for "search string" text
* The active Search string isn't visible
* There's no indication both Search and Find are active
* Search and Find must both be cancelled to view all items -
* You cancel a Search by clicking the round ( x ) button to the LEFT
* You cancel a Find by clicking the flat X at the FAR RIGHT
* Performing a Search while Find is active can result in an empty list, but a new item displayed

Misc -
* Find doesn't update the list item count
* Find is immediately below Search, but the field is different and font is larger
* Command-Option-F doesn't return focus to the Find field if it is already open
