@yaichenbaum This PR has become too complicated because it covers portions of code that have changed a lot. I propose to reapply the changes from the current state. I need to know what to do with the tooltips (see my post above).

@cinqmilleans Can you resolve the merge conflicts?

@yaichenbaum This pr changes the order of the layouts from smallest to largest (column / detail / tile / grid small-> medium-> large), in the context menu and in the navigationtoolbar (which does not currently display the same order) . This is the order that is used for the shortcuts. So I did not apply your changes.

As discussed in the issue, we would prefer to keep the current order since it's arranged by what's used more often.

@yaichenbaum Ok for me. The changes you proposed only modify the tooltips. I'll edit to keep the current order.

Correct, that was just the general idea 🙂

[cinqmilleans]

@yaichenbaum It is done.
