merkatorgis/streetsmart-qgis-plugin ? reverse-engineered prompt

Build me a QGIS plugin for Cyclomedia StreetSmart that lets people browse StreetSmart imagery right inside QGIS.

I want a simple setup where the user can turn the plugin on, enter or manage their StreetSmart access details, and then open a StreetSmart viewer panel from QGIS. From there they should be able to click a location on the map and view the corresponding panorama, move around between nearby images, and use basic tools like measuring and checking geometry against the map.

Make it feel like a normal QGIS plugin, with a clean settings screen, helpful messages when something goes wrong, and support for loading in a browser style viewer if that’s the easiest way to show the StreetSmart content. If you need to look up current StreetSmart or QGIS plugin docs online, go ahead.
