attach-plus

In the DSH web input bar, the single + button has to serve double duty as both the command-menu trigger and the file-upload entry point, which makes it hard to tell at a glance whether you are about to run a command or attach a file. attach-plus splits those two jobs into separate, semantically clear controls: the command button is relabelled with a / glyph (click and keyboard behaviour are unchanged), and a new + round button opens a three-tier menu for images, documents, and other files, invoking the browser's native file picker. Images flow through DSH's native draft pipeline with thumbnail preview and quota checks (5 MB per image, 20 images per message, 100 MB total) and are sent as image blocks alongside the message. Documents such as PDFs, Office files, CSVs, and plain text, as well as any other file type, are written to the session workspace's uploads/ directory via the plugin API, and a trailing Attachment: path reference line is appended to the draft so the model can read the content with its built-in file tools. The result is a cleaner input bar where running commands and attaching files each have their own affordance, and providing document context to the model becomes a single click instead of manually pasting a path.
