Very early in my career I made friends with the business’s sole Lotus Notes administrator, "the email server guy." He was pretty proud of what it could do, and I sometimes get nostalgic for the admin UI.
I started this project because I was nostalgic for Lotus 1-2-3, but I really really really loved WordPerfect. I'm afraid of starting that project, however, as it might take over my life :) I used to use WordPerfect 5.1 on a 386 PC to edit my school newspaper with multiple columns, graphics, custom fonts, etc. No WYSIWYG, just the power of Alt+F3 (Reveal Codes)!
As a big fan of WordPerfect on my first DOS machine (286 clone), I agree. I respect authors like GRRM for sticking with WordStar, but whenever I get nostalgic and wondering about WordPerfect in DosBox, I remember I use emacs and typst. All the good things about WordPerfect, but vastly superior.
I keep seeing ads for expensive "writerdecks" that run between $500 and $1200 and have a bare-minimum OS that is intended for distraction-free writing. I keep wondering how these are any better than an old laptop, FreeDOS, and WordPerfect 5.2, except as Veblen goods.
