Editing the General UI

Most of the Admin Page ui is in html files in the Server Side Code/views/ folder. 

Since most pages have the same basic structure, most admin pages are generally placed inside template.htm.

Public pages are nested inside publictemplate.htm

Editing the Form Structure/text

The forms are being generated in Server Side Code/js/script.js.

Search and replace any form text you wish to change from this file.

Editing Notification Titles

The general notification title can be changed from: Server Side Code/controllers/ApiController.php line 191:

    function sendPushNotification($f3, $title, $body, $topic='news')
