Known Issues & Limitations

The following are known issues and limitations that we plan to tackle:

    Large text blocks will kill responsiveness! Use the LargeText widget.

    The widget catalog is aimed at developer tooling, not general consumer polish: no rich text, tree widget, or date picker yet.

    There is no robust theming system. Some widgets take an accent color; custom button styles mean implementing your own (the stock Button is a usable reference). Styling can still be verbose at times.
