What
Claude Code now tracks, per plugin side panel, whether the user has already been asked about it or has dismissed it (via new pluginPanes.asked state). Placement of a panel is also gated on how wide the terminal window is: panels that don't fit below a size threshold are marked as "not placed" and show a message explaining that they'll open once the terminal is widened or the user reopens them.
Why
This keeps plugin panels from prompting repeatedly once dismissed and avoids trying to cram a side panel into a terminal window that's too narrow to show it properly.
