Artboard Switching and Zoom Level
Zoom level should be maintained when switching between artboards, whether it be by clicking between them in the Artboards panel, CMD+PgUp / CMD+PgDwn or in the status bar.
As for now, we can use these scripts to jump between artboards with the zoom level kept: https://onthehead.com/#cat-ais-view
I mapped these to Wn + PageUp/Down hotkeys using an external utility, works for me.
I would like it to work in the same manner as InDesign works with pages/spreads. When you navigate between pages (that would be artboards in Illustrator) with shortcuts or mouse buttons, the zoom is maintained. If you double-click on a certain page (artboard) in the panel, it becomes active and Fits in Window.

It would be very helpful to get this option to choose - it's very painful to name & sort a big number of artboards and it keeps zooming into the just named, then having to zoom out again etc.
There should be an OPTION to make it work that way, because some people USE current behaviour.
I would use both, depending on task.
So I vote for this, but only as an option. Not a DEFAULT option.
