Lightbulb: GUI applications traditionally exchange data between each other (like CLI piping) by saving to disk or offering data via a drag and drop protocol. I wonder if there would be value in having an application that visually allows you to construct a pipeline from application to application.

Something like an application called "Flow" where you drag the 1-window GIMP into Box A, then a photo-cataloguing app into Box B.

I could also see this being something doable from a system menu. You see a list of open applications and create a visual linkage/workflow between them.

I've also wanted a Wayland compositor feature where you drag data from 1 application to another, and the compositor jumps in to offer how to transform the data between them. Say if App-A only offers MP3s, and App-B only accepts FLAC, the compositor could trigger an app to negotiate transforming/re-encoding that data between apps (and then offer to App-B).

I have some bad, contrived examples here.
