What would your ideal desktop workspace be able to do?

I started building Sunder because I kept running into the same feeling:

Most workspace apps are useful, but after a while they start shaping the way you work.

You can customize them a bit, but there is always a point where you think:

"I wish I could just add this one thing."

That is the idea behind Sunder.

It is a local-first desktop workspace that can be extended with installable packages. The first package family is focused on AI agents, because that was the workflow I personally needed first.

But Sunder is not meant to be only an AI app.

My hope is that people can eventually build packages for all kinds of workflows: developer tools, dashboards, automation, research, internal tools, personal productivity, or things I would never think of myself.

So I am curious:

If you could add one missing capability to your desktop workspace, what would it be?
