Development is not progressing as fast as we would like. Additionally, we had to add a style viewer to the implementation, which replecates the functionality of Adobe XD. We will be able to provide the release of the new Qt style and template for Adobe XD not earlier than 3-rd quarter of 2022. While I'd suggest using our old styles - they are still relevant. The next update will be released soon, there will be a lot of fixes for old styles.
See screenshot of our style viewer prototype below:
Thanks for your question. The release of this app is postponed to next year 2023. We are very far advanced in development, but are not yet ready to announce a release date for the alpha or beta version. Most likely before the end of this year we will make an announcement of our plans regarding the mechanism for developing new styles based on this Design Tool. Now we almost fully support the Adobe XD format, including - palettes, states, inheritance, components, artboards and others.
