Feature to hide all dms in a space from general view

### Your use case

#### What would you like to do?

I have a space with work related things.
I would like to hide this space's dms from the general (non-space) view.

#### Why would you like to do it?

Less clutter.

#### How would you like to achieve it?

Perhaps an option in the space to set it so the space's channels don't show up in the general view that is editable per-user.

### Have you considered any alternatives?

Putting my personal stuff into it's own space, but this is just not feasible.
