Steps to reproduce: 1. Select Icons-only Task Manager as task manager. 2. Pin some tabs. 3. Switch into any Alternatives. 4. Switch back to Select Icons-only Task Manager. Expected result: Previously pinned tabs are in their places + prev settings are remembered. Actual result: No pinned apps + default settings.
Individual instances of each applet have their own config. Using Alternatives to switch is the same as removing and re-adding. Config is lost.
