I’m horrfied every day at work that copy/paste still is an issue. All my coworkers and customers are still struggling with copying some data, switching to another program, pasting it, switching back, copying some other data, and so on, especially when needing two or three data frequently.

In Windows, a (bad) solution is using win+tab, which literally no one knows about, much less uses.

In Linux (and should be in Windows too), it is trivial to implement buffers (say 0-9) to store and retrieve clipboard data for subseconds access.
