I understand your point. I am an medm user. But as a complete CSS novice I downloaded the CSS nightly build, ran a single unzip command, and had a nicely working CSS system. Building CSS from scratch is a challenge, but installing and using a pre-built version is not.
The conversion tools from medm to CSS and caQtDM are working quite nicely, particularly when the medm displays themselves are well-designed (i.e. text actually fits in the text widget, menu widgets have the correct datatype (decimal vs string), etc.

> In summary, I would like to develop a new display manager around Dear
> ImGui and any feedback or comments on the idea would be great.
