Org-transclusion -- now on ELPA!

Are there any attempts at creating a digital interface emulating a physical Luhmann slipbox? I think cards being “before and after” one another is something we are sorely missing in org-roam, and having something like that would be very nice. For instance, right now it’s hard to make ‘anonymous’ notes; some concepts cannot be named, like certain theorems in math. But anonymous notes would be of value if they were before or after certain notecards, with context generating its value.

I tried to do this with a bunch of windows (e.g. 4 horizontal windows) that scroll through the slipbox, but it seems org-transclusion is a much better alternative for implementing something like this.

EDIT: Is the imgur link (first gif) not working for others?
