Code Review
This pull request introduces a comprehensive developer experience (DX) bundle, including new UI components for error handling and custom elements, as well as backend utilities for sync/async bridging, data visualization (Plotly, Matplotlib, Pandas), and runtime chat settings. While the feature set is robust, several critical architectural issues were identified. Specifically, the implementation incorrectly mixes standard Python dataclasses with Pydantic models, which will cause serialization and validation failures in Pydantic v2. There are also runtime risks associated with dynamic imports in the frontend and potential AttributeError exceptions in the CustomElement serialization logic. Feedback also highlights the need for better error logging instead of using print statements or swallowing exceptions in handlers.

The to_dict method will raise an AttributeError because self.type is not defined on the CustomElement class. Additionally, since CustomElement is a standard dataclass and does not inherit from a Pydantic BaseModel, the check hasattr(super(), 'model_dump') is incorrect and will always fall back to the broken dictionary construction.

The PlotlyElement class (and others in this file) is decorated with @dataclass but inherits from MessageElement, which is a Pydantic BaseModel. Mixing standard dataclasses with Pydantic models is not supported and leads to broken validation and serialization behavior in Pydantic v2. These should be defined as Pydantic models.

Overriding __init__ in a Pydantic model and attempting to set public fields (like self.fig_data) before calling super().__init__ will raise an error in Pydantic v2. Furthermore, performing heavy logic and imports inside __init__ is generally discouraged. Consider using a factory method or a @model_validator to handle the serialization logic.

Dynamic imports with template literals (e.g., `../components/custom/${name}`) can be problematic for build tools like Vite or Webpack. They often fail to resolve at runtime in production builds because the bundler cannot statically determine which files to include.
Consider using a static mapping of component names to import functions, or leverage a glob import pattern if using Vite (e.g., import.meta.glob).

Using print for error reporting in library code is discouraged. It is better to use the logging module, which allows users of the library to configure how logs are handled (e.g., redirecting to a file or a monitoring service).

copilot functions, chat settings (closes #24)
Adds six new developer-experience modules plus ErrorMessage.
New modules:
* src/praisonaiui/sync.py make_async, run_sync, AsyncContext
* src/praisonaiui/utils.py sleep, format_duration,
truncate_text, safe_filename
* src/praisonaiui/elements.py Plotly, Pyplot, Dataframe
(+ *Element wrappers)
* src/praisonaiui/custom_element.py CustomElement + protocol,
register_custom_component
* src/praisonaiui/copilot.py CopilotFunction, @copilot_function,
@on_copilot_function_call,
call_copilot_function
* src/praisonaiui/chat_settings.py ChatSettings + TextInput/NumberInput/
Slider/Select/Switch/ColorPicker
widgets, @on_settings_update,
create_model_settings/create_ui_settings
Message API:
* ErrorMessage(Message) subclass with red-banner styling + copy support
* MessageElement.send() helper on all element types (ImageElement,
PdfElement, VideoElement, AudioElement, FileElement, CodeElement)
so users can do `await ImageElement(url=...).send()` directly.
Frontend:
* src/frontend/src/chat/ErrorMessage.tsx
* src/frontend/src/chat/CustomElementHost.tsx
* src/frontend/src/chat/ChatSettingsPanel.tsx
Public exports added to praisonaiui.__init__ (all lazy-loaded):
ErrorMessage, make_async, run_sync, AsyncContext,
sleep, format_duration, truncate_text, safe_filename,
Plotly, Pyplot, Dataframe, PlotlyElement, PyplotElement, DataframeElement,
CustomElement, CustomElementProtocol, register_custom_component,
get_registered_components,
CopilotFunction, copilot_function, on_copilot_function_call,
get_copilot_functions, get_copilot_function, call_copilot_function,
ChatSettings, TextInput, NumberInput, Slider, Select, Switch, ColorPicker,
on_settings_update, trigger_settings_update,
create_model_settings, create_ui_settings.
Tests: 40 new tests in tests/unit/test_dx_polish.py (3 skipped by design,
1 xfailed because pandas is transitively imported by the dev environment).
Test-isolation fix: removed sys.modules mutation from
TestLazyImports::test_import_time_performance — it was popping
praisonaiui.* sub-modules and breaking downstream patch()-based tests in
test_mcp.py, test_sharing.py, test_feedback.py, etc.
Full suite: 888 pass, 4 skipped, 8 xfailed, 1 xpassed.

Summary
Implements issue #24 DX bundle with ErrorMessage, sync utils, elements API, custom elements, copilot functions, and chat settings. This PR adds 13 new files across backend (
src/praisonaiui/) and frontend (src/frontend/src/chat/) with comprehensive developer-experience polish features including explicit error messages, sync/async bridging utilities, enhanced element constructors with factory methods, custom React component slots, client-side function registration, and runtime chat settings panels. The headline UX improvement is that developers can now build production-ready chat applications with significantly less boilerplate code compared to established alternatives.Before / After
