I would love to have an option that when I change a tool, my layer changes accordingly.
Imagine texts: I would be able to optionaly customize this in document setup, so that I would tell Layout which layer to insert texts by default. I would hit the text tool and the layer would change to the default text layer I had chosen.
This could be finetuned to extreme scenarios too: If I had two text layers and I happened to be typing texts, Layout would assume that the current Layer was the one to insert objects. If I had been working on Dimensions and would hit the text tool, Layout could display a floating box to allow me to choose which of the text layers I would want to work with. If I would ignore that and type, it would use the first on the list.
This way I would never happen to bump in the same recurrent issue, of drawing in the wrong layer.
Example: dimensions being created on the bottom viewport layer where I have 3 stacked viewports on top, that when I turn on, mask everything, dimensions included.
