New, choose a layer imagery cluster.

[Allroads]

We all use JOSM different, each session has it's theme, where you work on.
This theme needs mostly several layers.
Worldly but also country layers (wms tms) to check.
Starting each time, you need to set up these layers in a established working sequence, with a visibility setting, controlling is also toggling between layers. All these layers must be there.

It would be nice, that we could save such preset imagery cluster (which is sequenced), give it a name and use it when starting JOSM, imagery layer cluster is set.

Now I open every time 4-6 imagery layers with a new session/Josm start.

Why:
Some plugins are annoying, they cooked in too much.
Like: Improve osm a Plugin provided by an external source.
There must be rules for it, a plugin is a help but, a plugin must never take over the layout basic working of JOSM.

Here I mentioned this imagery layer cluster as a idea.

That's why I like there must be rules, a kind of a certificate for plugins.
What they must do or not.

Are there such rules?
