From ce8dd82bb0557f667c8e953ee31d020e6025b4df Mon Sep 17 00:00:00 2001 From: Greg Pomerantz Date: Sun, 31 May 2026 23:20:21 +0000 Subject: [PATCH] Remove duplicate browser state and fix sort mode toggle - Remove currentBrowserState global and SetBrowserState from browser package - Browser now receives sortHandler as a parameter instead of using global state - Fix sort mode toggle: reload pages after clearing cache (was showing 'Loading...') - Add String() methods to all UI element types for debugging - Add e2e tests for sort mode functionality (5 tests) The editor now owns all state; the browser is a pure function receiving state and handlers through parameters. --- internal/browser/layout.go | 22 +- internal/editor/state.go | 7 +- internal/test/e2e/browser_files_test.go | 3 +-
