Usage:

You can access the Saved views panel by going to the view section of the N-Panel or by pressing CTRL+W(which can be changed in the preferences).

In the panel, you can save new views by pressing the + button or remove existing views by pressing the - button.

Thumbnails are automatically captured and saved.

You can switch between the saved views by selecting its thumbnail or selecting its name from the list.

Local view state is also saved while saving the views so you can go back to local view just by selecting the saved view.

There is also a Camera list to quickly switch between camera views.
