I am going through the ui and putting on the polish for the upcoming 13 release. My focus is on style but I know there are typos and other errors. As you work within FreePBX please take note of these errors and file a ticket at issues.freepbx.org . You may put multiple errors from a single module in to a single ticket.
Also if you have suggestions on improving tool tips please file an improvement ticket at issues.freepbx.org. again, multiple tooltips within a single module may be filed together.
