Question: Is this idea meant to work like in macOS, where you can pin files and folders to the dock, or as an temporary place instead of the clipboard?
Since I’m not sure which one you’ve meant, I’ll give an opinion on both:
[…] work like in macOS, where you can pin files and folders to the dock, […]
To be honest, I don’t think that would work well inside of GNOME, at least not the vanilla one.
On macOS, the dock is part of the, let’s call it, “work view”. Its in the same view as where you work inside an application window or with the desktop files.
In this environment, having the ability to pin files and folders to the dock can make sense.
On GNOME though, the dash is part of the activities view. It is separated from where you work and is instead where you manage your open apps.
Since this is in another view, separated from where you would use the files and folders, I don’t see it would be a great fit.
[…] as an temporary place instead of the clipboard.
I could see this work, potentially.
The idea doesn’t sound bad on paper: You can temporally place something you need into an drop place, and drag it into another app where you need it.
That being said, this is something that would happen in the “work view”, so I could see this working better as an separate UI element than as a part of the dash.
Also, there are quite some open question.
Like, say I move a file with it: Does it move or copy the file?
Or would it be possible to drag tabs into it?
I could see the argument that you should be able to drag, say a Epiphany tab into the space. Then you could drag it out on a new workspace for a new window. Or you could drag it into a text document to make a link.
I could see this work, but it would need to be worked out in more detail. What can it handle, how does it handle it, how would you control it.
And if a good design concept has been made, it could be tested with an extension.
I wouldn’t say the idea is dumb, but there are many questions that would need good answers.
