PowerShell and Out-GridView are a rudimentary version of this. It looks like:

PowerShell cmdlets output .NET objects with properties, in that example Get-Process makes an object-per-running-process with properties for Name, Id, and more. Out-GridView takes arbitrary objects and draws a resizeable GUI window with a list of the input, properties as columns, sortable, filterable, and has options to use it as a basic "choose one of these and click OK" user-prompt. It works with the grep-analogous cmdlet:

    select-string '<regex>' <filename(s)> | out-gridview

    # shorthand
    sls foo *.txt | ogv

and the output is the filename, line number, line, and regex match groups, of each match. [This dates back to Windows XP SP2, in 2004].

If we're talking about things we imagine in terminals, one I have wanted is multiple windows for making notes, similar to having a text editor open constantly reloading a file on any changes and running some terminal commands with tee into the file, but better integrated - so I could keep a few useful context results but ignore logspam results; and "keep" in another window without having to copypaste. Something better integrated - it always gets all command output, but disposes of it automatically after a while, but can be instructed to keep.
