   Updating this issue to follow the Feature Request template so it is not auto-closed:

   • I have verified this feature I'm about to request hasn't been suggested before.

   Describe the enhancement: When an assistant message contains a long code block (desktop/web UI), the copy button sits at the top of the block and only appears on hover, so it is gone by the time you scroll down through the code. Request: a slim sticky header on each code block (language label + always-visible copy button) that stays pinned while scrolling through tall code, like ChatGPT's code header. No height cap — the block still extends fully.

   System info: macOS 27.0, desktop app (dev build from dev), opencode 1.18.34. Repro: open any session, render a code block taller than the viewport, scroll down — the copy button scrolls away with the top of the block.

   On the flagged duplicate #28942: related, but that issue asked for hover-or-sticky on the button alone, was auto-closed for template non-compliance, and never resolved. This request goes further (a full header strip with the language label, always visible) and I have a PR implementing it: it supersedes rather than duplicates #28942.

   Thanks for adding the Feature Request details, verification checkbox, and system/reproduction information. The issue description itself still contains only the original one-line request. Please move the template content into the issue description so the issue uses the required template.

   Thanks for the detailed request, @imsoul11! You're asking for a slim sticky header on code blocks in the desktop/web UI, with the language label on the left and an always-visible copy button on the right. It would stay pinned while you scroll through a tall block, so you can copy from anywhere without scrolling back up.

   In the current code the copy button sits at the top of each block and only appears on hover, so what you see is how it was built. That makes this an improvement rather than a bug. Maintainers will consider it, and your PR will help with that.

   One small thing: the issue says opencode 1.18.34, which is a v1 version, but a desktop build from dev is v2. Could you check the version your desktop app shows? If it really is 1.x, please note that v1 only gets critical fixes.

   • Copy button on code blocks should appear on hover (like Claude) or be sticky (like ChatGPT) #28942: earlier request for a hover-only or sticky copy button on code blocks. It was auto-closed because it didn't follow the issue template, not because of the idea itself.

    Thanks for the review! Checked: this checkout's packages/desktop/package.json, packages/app/package.json and packages/opencode/package.json are all version 1.18.34 on dev — so the reported version is correct for a dev build from this tree. Happy to re-verify against a different version if maintainers want that.
