My company has a custom header that they'd like to have at the top of all applications. We've had some difficulty trying to add this header on to APEX applications in APEX 5.1 for Universal Theme.
We've created a master theme app and made css and html changes to the templates in that app, so that other applications could subscribe to it and get the changes. It seems like the way we are currently doing it may cause issues down the line if/when the templates are updated for future versions. Has anyone else ran into this requirement (custom header above the APEX Header that sticks to the top of the screen) and successfully implemented it?
