Collection grouping enabled by default

**Is your feature request related to a problem? Please describe.**

I created two collections: `sections` and `articles`. Each article must be assigned to a section. For convenience, I added in the config

```
view_groups:
- label: Section
field: section
```

I would like to always open the list with a grouping selected.

**Describe the solution you'd like**

Ideally, I could configure a default selection so that initially when the list opens, the entries are grouped

```
view_groups:
- label: Section
field: section
default: true
```

It would be logical that only one view group can have `default` property or that last wins

**Describe alternatives you've considered**

I noticed that the selected group is preserved on navigation but not after full page reload.

A simpler solution could keep the chosen group in local storage so that it's applied after refreshing the page
