# Make It Even Faster ## Scrolling and large libraries The sidebar is drawn alongside every page, so its sorting work can affect scrolling elsewhere in the window. Library ordering now looks up each row's position once per sort instead of repeatedly searching the full saved order. This reduces the work each frame needs for large libraries while preserving your chosen sort, pins, and folders. The main window draws as needed and uses the platform's frame pacing. The player bar and mini player visualizers draw at the **Frame rate** chosen in Settings > Appearance, 60 by default; a lower rate uses less power. The MilkDrop frame-rate setting applies to its separate visualizer window. ## API rate limits Spotify limits how often apps can ask for information. Spotifast normally shares this allowance with other listeners and several other music players. When that shared connection is busy, your library and search results can take longer to load. The top bar shows a spinner while you wait; hover over it to see whether Spotifast is updating your library, checking for updates, or waiting for Spotify. Your playlists and Home show what they showed last time until the update arrives. You can reduce those delays by creating a **personal Spotify app**. This is a connection registered to your account on Spotify's developer website. You do not need to write code or install another player. Spotifast offers this setup once after you sign in with Premium. Choose **Set up personal app** to open Settings, or **Keep shared app** to continue as you are. You can set it up later in Settings. A personal app gives many of your searches and library requests a separate allowance. Creating one is free and takes a few minutes, and Spotify requires a Premium account. If you create several personal apps, they share your account's allowance, following Spotify's [July 2026 quota update](https://developer.spotify.com/blog/2026-07-23-web-api-quota-updates). Some features still use the shared connection, and your personal connection has limits too. ## Shared coverage stays active Your personal connection searches songs, artists, albums, podcasts, and episodes. The shared connection finds playlists and supplies features Spotify does not make available to personal apps, such as recommendations and related artists. Search results appear as each part is ready, so a delayed playlist search does not hold up the songs. Spotify allows personal apps ten search results at a time for each type, compared with twenty on the shared connection. Setting up playback on this computer also helps playlists load faster. Spotifast can load playlists that would otherwise use the shared allowance through its music connection instead. [How it connects](/how-it-connects/) explains which connection each feature uses. ## Make a Spotify app 1. Open the [Spotify developer dashboard](https://developer.spotify.com/dashboard) and sign in with your Spotify account. Spotify asks that it be a Premium account. 2. Click **Create app**. Any name and description will do; nobody else sees them. 3. Under **Redirect URIs**, add exactly: ``` http://127.0.0.1:8989/login ``` 4. Tick **Web API**, accept the terms, and save. 5. The app's page shows its **Client ID**. Copy it.  ## Use it in Spotifast 1. Open **Settings**, find **Personal Spotify app**, and paste the Client ID. 2. Click **Authorize**. Your browser opens Spotify's sign-in for your app. Spotifast verifies that it belongs to the same Spotify account, then shows **Personal app ready**. Your playback setup stays the same. Select **Remove** to stop using your personal connection and return to shared access.
