 - Added the possibility to configure embedding providers in the app settings as a prototype preview feature. Embeddings are necessary in order to integrate local data and files.
 - Added the writer mode as an experimental preview feature. This feature is just an experiment as we explore how to implement long text support in AI Studio.
 - Improved self-hosted LLM provider configuration by filtering embedding models.
+- Fixed a bug where you couldn't move a chat to (another) workspace when the workspaces were docked to the left side and were collapsed.
+- Fixed a bug when you replaced a chat with a new chat, and the workspaces were docked to the left and were collapsed; then, the previous chat was not removed from the workspace.
