Firstly congratulations on your expansion into other states.
At this stage we aren't looking at Practice Groups being grouped by state, but I do have a suggestion which may help.
If you have too many practice group tabs across the bottom of the screen, and would like to limit the number, you could use the Security/User Access settings to restrict access only to the tabs each user needs.
For example, if the user 'Andrew' only needs to see the practice group 'Adelaide', you can go to System followed by Security, and change the Access settings for that user to only allow access to only the Adelaide Practice Group as below.
I hope this helps. If you would like further assistance with this, please contact our Helpdesk using one of the support options available on our website: www.smartsoft.com.au/support
