Here’s a clearer summary of what I’m looking for:

If valid, keep the user logged in; otherwise, log them out.
Customizable Button Colors

Allow changing the colors of both the login and EPG buttons.
Video Search

Add a search button for users to find videos.
Scrolling Text/Ticker

A fixed scrolling text area at the bottom of the channel.
Customize background color, font size, font color, scroll direction (left-to-right or right-to-left), and speed.
Fetch the text content from a JSON API.
Preroll Video

Play a preroll MP4 (via a URL) before all videos.
EPG Page Fixes

Correct the wrong time formatting in the EPG.
Optionally let the user click on a channel to watch it (toggle on/off in the script).
M3U8 links will be included in the channel data.
