From c5864fadf6b61fc983df653f76f351d9d98acf5c Mon Sep 17 00:00:00 2001 From: vikingowl Date: Thu, 1 Jan 2026 02:39:24 +0100 Subject: [PATCH] fix: memory leaks, mobile UX, and silent failures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix memory leaks in ui.svelte.ts and sync-manager.svelte.ts by storing bound function references for proper addEventListener/removeEventListener - Make conversation action buttons visible on mobile (opacity-100 when isMobile) - Replace silent console.error calls with toast notifications for user feedback - Remove ~35 debug console.log statements from production code Files: ui.svelte.ts, sync-manager.svelte.ts, ConversationItem.svelte, ChatWindow.svelte, CodeBlock.svelte, MessageActions.svelte, MessageContent.svelte, +page.svelte, builtin.ts 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- TODO.md | 185 ------------------ .../src/lib/backend/sync-manager.svelte.ts | 43 ++-- .../src/lib/components/chat/ChatWindow.svelte | 45 +---- .../src/lib/components/chat/CodeBlock.svelte | 3 +- .../lib/components/chat/MessageActions.svelte | 3 +- .../lib/components/chat/MessageContent.svelte | 3 -
