But the core with its single thread processing and constant hangs, requiring you to repeatedly hit C-g at least once a day, is first in line for "facelift".
Just wanted to clarify, to me that's timeless. Modern would be having modern menus, pop-up configuration screen et al.. All the candy that appeals to a less experienced user, who worked with Idea, Sublime of VS code before.
But I've never really got the idea of why emacs should appeal to less experienced users. I think that's misguided: the entire point of Emacs is that you write some emacs lisp. If you're not interested in writing any lisp, then you definitely shouldn't bother with emacs (I used emacs intensively for 20 years and am the author of Emacs packages). And if you're less experienced and looking for Idea/Sublime experience then at this point in your life there's a good chance you aren't interested in writing lisp.
I've been using emacs with the "lucid" build since forever, as it's the leanest build that still gets a graphical window working on X11 and see none of the actual "toolkit".
I guess the pgtk build is required nowdays for native wayland support.
My comment is an honest reflection of long-time Emacs usage. When I started, years ago, I just couldn't wrap my head around the fact that there were no tabs for every file anymore - the concept that was seemingly ingrained into my programmer's brain - almost in every IDE/editor I used before Emacs, I had tabs and a navigational panel on the side. I complained and demanded my tabs, asked on forums and called it "bullshit", when people calmly told me that I truly don't need them. Later I realized - they were right.
Slowly I learned that the wise choice is to remove any distractions - you don't need a minimap, side-panels, complicated modelines, and even line-numbers shown all the time. All that can be activated purposefully, on demand and then toggled off again. These "visual clues" are in fact not so much even distractions but micro-bombardments of your brain neurons - you think they are helping, while in fact they are slowly eating up your neural capacity, to the point that the brain just stops even paying attention to them and they become almost useless waste of your screen estate.
I'm not saying that this all generally true for every case and every user - some prefer certain ways, and it's great that we have a system that is able to satisfy any whim, but it's worth sometimes questioning yourself - am I enslaved by my own mental habits?
