wtf is claudeplusplus?

Claude++ is a Chrome browser extension that adds a set of quality of life improvements to the claude.ai website. Everything it stores stays on your own device, so there is no account to sign up for and no separate server involved. One feature lets you assign a color to a project so its chats show a matching tinted icon in the sidebar, making it easier to see at a glance which conversation belongs to which project. Another adds a way to create a brand new project directly from an existing chat, instead of only being able to file a chat into a project that already exists. There is also a delete guard that makes deleting a project safer: it renames the confirmation dialog to include the project's name, warns that all chats, files, and artifacts inside will be lost, and requires typing the exact project name before the delete button becomes active. The extension also changes the browser tab title to show an hourglass icon while Claude is still generating a response, a checkmark if it finished while you were on another tab, or a warning icon if the response ended in an error. Another feature lets you select any passage of text in a chat and ask a follow up question about it, with the answer appearing in a card in the margin next to the highlighted text, kept in a separate temporary conversation so it does not clutter your main chat history. Other additions include a draft mode, similar to a mode switch in Claude Code, that lets you compose a message freely without any risk of accidentally sending it, scroll navigation buttons and keyboard shortcuts for jumping between your own messages in a long chat, and a download button that saves an entire conversation as a structured XML file, following only the active branch of the conversation so edited or regenerated replies are not duplicated. To install it, you load it as an unpacked extension through Chrome's developer mode, since it is not listed on the Chrome Web Store.
