[Package Idea]: An extension for XREF that works like this package?

[skyler544]

First of all, thank you for deadgrep! Second, I'm sorry for abusing your issue tracker like this. This is more of a discussion topic if anything.

The idea goes roughly like this:

The display of the *xref* buffer is pretty similar to this package (see screenshot), which makes me wonder; how nice would it be to have a little more control over *xref* buffers, the way you can take advantage of multiple deadgrep buffers?

1. Having multiple *xref* buffers with specific contexts (I think that currently this isn't possible).
2. The ability to redo an xref query the way you can with deadgrep (it doesn't look like revert-buffer can handle this in xref)
3. A nicer, more readable display like what you've created with deadgrep (I modified xref--insert-xrefs to have spaces between groups in order to get the effect seen in the screenshot; I guess that since that's hard-coded, creating an xref extension would take more than just calling that function in the client package)

I'm basically just spit-balling here, but I've also recently started taking a crack at improving my elisp skills, so if you have any interest in this idea I would be interested in helping make it happen. :)
