The client explorer includes a search feature where you can search by customer, pet, phone, address, email, first name or last name by choosing your option in the drop down menu.
For example, you can choose last name, enter M and get all last names starting with M.
Or, you can choose pet name and enter Ran to get all pet names starting with Ran.
There is also a sizing option. At the bottom of the explorer, there is a blue tab that you can move right or left to increase or decrease the size of the font of the explorer.
You can also click the left margin and drag it to expand that window.
