We added more information on what the app is syncing - for each app you connect.
We've been gradually adding ways to understand and control what happenings during initial indexing. Starting with this release, you can now see sync status for each app (source), as well as which files are being processed.
To check it out, click Preferences (cog icon in the sidebar) and go to File Scheduling (in the Preferences sidebar). Under the section Queue you'll see all the sources that are actively syncing / indexing. Click the + for additional details on the file types in that app.
We hope this helps manage indexing for a smoother start with Curiosity!
