[Feature Request] Enhanced Diff View, Flexible Sidebar, and Local File Tracking

[AriajSarkar]

I would like to propose a set of UI/UX improvements to the T3 Code interface to streamline the development workflow and reduce the need to switch back and forth between the browser and a local IDE.

1. Track Local/User Changes
   Currently, the diff view appears to focus primarily on thread-specific changes.

The Problem: It is difficult to see changes made locally that don't necessarily belong to the current T3 Code thread.

The Proposal: Add a section (perhaps named "Local Changes" or "User Changes") that shows a diff of all local modifications within the workspace, regardless of the active AI conversation.

2. Improved Diff Navigation & UI
   The current toggle for the diff section could be more intuitive.

The Proposal: * Replace the animated +/- icon with a standard arrow/chevron icon (e.g., <-) or an arrow paired with a clear "Close" label.

This provides a more standard "back" or "collapse" affordance that is easier to recognize at a glance.

IF 2nd point implemented, then no need for 3rd point

3. Flexible Sidebar & Squeezable UI
   The current sidebars have a fixed minimum width that limits how much screen real estate can be dedicated to the code/editor.

The Proposal:

Adjustable Width: Allow both the left sidebar and the diff section to be "squeezed" (resized) further than the current fixed minimum.

Collapse to Icons: Implement a "Mini Sidebar" mode similar to ChatGPT, Gemini, or DeepSeek. When the sidebar is collapsed, it should hide text labels and show only small icons to maintain functionality while maximizing the workspace.

there are 5 issues in one here

@maria-rcks
Is 'too many issues in one' a valid reason to close this?
Having the permissions to close an issue is one thing, but I’d hope there is a clear technical reason for doing so beyond just the count.

you can open issues for each one individualy
