This commit introduces the necessary logic and UI controls to allow users to switch the Flow component layout between vertical and horizontal orientations.
* **`Flow.svelte` Refactoring:**
* Updates logic for calculating level offsets and node positions to consistently respect the current flow orientation.
* Adds a control panel using `<Controls>` and `<SwitchButton>` components.
* Provides user interface elements to easily switch the flow layout between horizontal and vertical orientations.
This commit introduces a new setting in the Interface settings that allows users to control whether the chat title is used as the browser's tab title.
The following changes were made:
- Added `useChatTitleAsTabTitle` to the `Settings` type in `src/lib/stores/index.ts`.
- Added a toggle switch in `src/lib/components/chat/Settings/Interface.svelte` to manage this new setting.
- Updated `src/lib/components/chat/Chat.svelte` to conditionally set the document title based on the `useChatTitleAsTabTitle` setting.
This commit fixes a UI bug where pinned chats would remain visible in the sidebar after all chats were archived from the Data Controls menu.
The `archiveAllChatsHandler` in `DataControls.svelte` has been updated to clear the `pinnedChats` store, ensuring the sidebar UI is correctly updated.
This commit addresses an issue where long filter tags at the top of the model selector dropdown were not truncated correctly and would wrap to a new line, causing layout issues.
- A hard character limit of 16 characters is applied to the filter tags within the `Selector.svelte` component. Tags longer than 16 characters are truncated with an ellipsis (...) directly in the code. The full tag name remains available in the tooltip.
- The `whitespace-nowrap` class has been added to the tag container to ensure that the tags remain on a single, horizontally scrollable line.
