Some users prefer to sort their users list by last name.
This can easily be changed in PracticePanther by users who have access to change company settings.
1) At the top right of the screen, click on your name, then on "Settings". Then from the menu to the left, select "Company Settings" or you can also click here.
2) Under the "Display Names" section, click the drop down list for "Users" and select "Last, First M".
What happens now?
This will update all your users in the background to be sorted by last name.
