Option to display layer numbers

[naoliv]

It's possible to toggle layers with Alt+1, Alt+2, etc, with 1 being the bottom layer, 2 the penultimate layer, etc

But when we have a lot of layers, like this, it starts to get difficult to quickly count or hit the desired layer number:

Could we have an option to display the layer numbers, please?
With something like this:

fix #17221 - display layer number in layer list, to ease using toggle layer shortcuts

Hi Team,

Thanks for this new enhancement, this will definitely help JOSM editors to identify the shortcut to switch between multiple layers, but it would be more helpful if the entire shortcut is displayed instead of just numbers as shortcuts are customizable, displaying entire shortcut key will definitely be a permanent solution and will not impact if shortcut keys are changed.

Current feature: [1][2][3]
Proposing feature : [Alt -1][Alt -2][Alt -3][Alt -4]

Nah, thats too much wasted space.

1) Isn't it an expert feature?
2) Could you please make this optional, at least with a preferences key?

see #17221 - make layer numbering an expert feature, configurable with layerlist.display.numbers advanced preference

Awesome, thank you Vincent!

[Don-vip]

You're welcome :) Thanks for the suggestion.
