global parameters which assumed to be plugin parameters

[danceb]

While checking all config parameters from the docs at [1] and [2] agains my config.json for switching to 2026-lts I came across a bunch of global parameters which seem to be better defined as specific plugin parameters. In addition there are general and plugin specific parameters with the same effect.

LayerTree

general	plugin specific
allowLayerTreeSeparators	allowLayerTreeSeparators addLayerSeparator (no effect)
allowRemovingThemeLayers	allowRemovingThemeLayers
allowReorderingLayers	-
disableImportingLocalLayers	-
flattenLayerTreeGroups	flattenGroups
importLayerUrlPresets	-
preventSplittingGroupsWhenReordering	-

Topbar - Search Parameters

general	plugin specific
searchFilterRegions	-
searchThemeLayers	-
searchThemes	-

ThemeSwitcher

general	plugin specific
allowAddingOtherThemes	hideAddThemeButton hideAddThemeLayersButton

So, why are these parameters defined as global ones? I think it would be a good enhancement to harmonize this parameters and define plugin specific settings within the plugin config blocks as there is no need for them to be global.
As the change to an new lts version is a good moment for such thing, as it could be clearly documented in the changelog, unfortunately we just had such version change and the next one would be in about a year ...
