For Slicer 4.11 nightly, I think the encouraged method for running modules with reduced interface is to hide elements of the main GUI specifically instead of using the previously used method of specifying the `--no-main-window` command line argument and adding GUI elements.

> Slicelets are regular modules, which hide user interface elements that are not necessary for the particular workflow and provide all required widgets on their module panel.
> 
> Hiding of user interface elements can be implemented in the setup method of the module widget class, using a combination of set…Visibility methods implemented in [slicer.util](https://github.com/Slicer/Slicer/blob/master/Base/Python/slicer/util.py#L1853).

Hi! What you are doing seems useful for the community, as many people have asked about a simplified segmentation tool based on Slicer. Are you planning to make yours openly accessible? I think a lot of researchers would appreciate that. Thanks!

Thanks for your reply. I am not a professional developer. I just want to make some of work more custom friendly. And if I could, I would love to make my work openly accessible.
