We’ve shipped a major set of upgrades to how Plain loads and syncs data, making the app feel much faster and more responsive, especially for workspaces with a large number of threads.

Rather than syncing your entire workspace each time you open the app, Plain now only fetches what’s changed since your last session. This dramatically improves load times on return visits and when opening new tabs.

We’ve also reworked how thread data loads across the app. Pages with long queues now load twice as many threads at once, with non-critical data fetched only when needed. Combined with the sync improvements, this makes navigating and scrolling through large queues feel much snappier.

In addition, we’ve optimized how thread counts and filters update in the UI. These calculations now run in the background, reducing lag when threads move between queues or filters are applied.

You’ll also notice better performance in other areas of the app, including the themes page, timestamp rendering, and local database operations.
