Can I map a hotkey to instantly open the add-ons page in the settings? I’ve looked through the keymaps but couldn’t find anything for this. If not, is there a way I can script this to happen?
And same question for the keymap page! I’m currently tinkering with the addons and keymaps plenty and it would be nice to have a way to just jump to those pages.

No.
But you can have the preferences window just not to be closed…or even put it somewhere into you main window 
Fair enough, thanks. It just feels like there should be a python command to call this up but I guess not. Actually haven’t thought about keeping it in a workspace tab, it’s a great idea!
Oh… yes… actually there is a type holding this informaton : docs.blender api bpy.types.Preferences.html active_section…
… and you can set it for example in the Python Console view via
bpy.context.preferences.active_section = 'ADDONS'
…for a “quick implementation” of a python command as button… i tried
…but this was a bit too quick… 
… this may be because i just had my first cup of

a very late reply, but thank you so much for this addon, this does exactly what i wanted!
