Gemini Widescreen Chat UI

This is a simple UserScript that fixes some of the UI annoyances in Google Gemini on desktop, making it much more comfortable to use—especially if you have a wide or ultrawide monitor.

Features:

Better Margins: Limits the chat and text input to 75% of the screen width and centers it. No more moving your head left and right to read long paragraphs on large monitors.
Input Box Fix: Fixes the text input field so the microphone and send buttons stay where they belong without overflowing or breaking the layout.
Wider Tables: Forces tables to use the full width of the chat container instead of being unnecessarily cramped.
Distinct User Prompts: Changes your messages to a dark blue background (#1a237e) with white text, making it much easier to differentiate your prompts from Gemini's answers at a glance.
Centered Code Blocks: Keeps code snippets centered and limits their width to 90% for a cleaner look.
Readability Tweaks: Slightly increases the line height so reading long AI outputs is easier on the eyes.

Customization:

If you want the chat to be wider or narrower, just edit the script in Tampermonkey (or your script manager of choice) and change the max-width: 75% !important; value in the .conversation-container block to whatever percentage you prefer (e.g., 60% or 90%).
