Feature request: Adding a gap around panels

[synecdokey]

I'm trying to get a gap around the panels, and around them, but nothing I've tried seems to work, as the .groupview is position:absolute. Since width and height are managed by dockview, a pure CSS solution seems out of reach, even using margins on the element is impossible.

A small gap property on the dock view would be appreciated, as I don't think CSS can solve it in this case.

What I'd want ideally is something that can look like this, which seems impossible at the moment unless I missed something:

There is a theme that is shipped with dockview but it's more of an experiment than something that was really intended for use which is similar to what you are describing here.

I did battle with getting a gap to appear on this theme and you can see the CSS code here, it's ok but not great... I do wonder if this could be better achieved though through the library exposing some kind of CSS variable define the gap size, let me have a see what can be done.

Within the docs website you can switch to this theme as below:
