I made a Chrome extension (which should be compatible with all Chromium-based browsers) and Firefox Add-on that hooks into the osm.org Edit buttons and redirects it to Rapid. Also, it integrates Strava heatmap support into Rapid as overlay imagery.
It’s an early version, and I’m sure there’s bugs, so please open issues (suggestions welcome too): https://github.com/emersonveenstra/rapid-power-user-extension/issues
Also, for those wondering, I am jumping back into osmdiscussiontracker development soon, I just needed to scratch this itch first :)
Happy mapping!
