Hi Bandaru,
Currently, the document editor does not provide support for number alignment, and the mentioned gaps issue is also related to this feature. We have already logged it as an improvement request on our end.
We usually have an interval of at least three months between the releases. At the planning stage for every release cycle, we review all open features once again and finalize features for implementation based on specific parameters, including product vision, technological feasibility, and customer interest. Once we have anything definite to share about this feature's implementation, we will move the feedback to "scheduled" status with the tentative release timeline.
You can track the status of this feature using the below feedback link:
