“More bloating” really?
Thanks for your flattering reaction to an open source plugin built and supported for free.
Imho, in any case, you are looking at this entirely the wrong way.
It’s not focussed on providing mobile users with more options, it is a plugin mostly designed to help make use of the extra real-estate when using Discourse on desktop or tablet by adding flexible sidebars.
Skinny phones (and small narrow tablets for that matter) do not make good targets for sidebars.
You prefer to have the desktop view remain just like the mobile view and not use the extra real-estate? Fine, go ahead and don’t install our plugin.
That said, it is possible to use it on mobile, see: Layout Settings - Discourse / Layouts - Pavilion (thepavilion.io)
