I found both links you suggest very interesting and impressive. But again part of my objection is that I do not want my screen divided in two, there is no need in 2020 to stick to this old tradition. I like more to be able to do this: https://www.youtube.com/watch?v=ILiL4m61BLw&t=4020s https://www.youtube.com/watch?v=ILiL4m61BLw&t=4020s I've used Emacs+AucTeX for long time and I agree with you that it is an excellent toolset. It is simply that with certain tools you will never ever even think to do something because it is just these 5 sec (too much) away. Like using colors in a table, or making algebraic manipulations directly on the documents on complex formulas. The tools we use shape what we do, subtly. If it takes you more than 5 min to make a drawing, maybe you take the decision not to do one. If takes more thant 30 sec to make a table, then same: maybe you get along without. In any case the burden of the technology will impose on you to get out of your writing focus to care about technical matters (open another applications, look into stackexchange...). I wrote that blog article to make a point for all those users who care about the quality of the interaction with the writing tool. I understand very well other tools allow more flexibility in some respects or wider compatibility, but in my personal experience none of the above mentioned tools can replace TeXmacs for creative technical writing or even for fast note taking. If you compare TeXmacs and LyX then you miss the point of my blog article. I've tried to carefully explain the particular nature of TeXmacs including some careful UI design choices which allows the UI to be out of your way and out of your screen. Ideally, there should be no button on the screen (look at Emacs, no toolbar), the free space on the screen has to be allocated for the document, with the right information popping up when needed. Moreover I do not want to see an approximation of the final result, that is not good enough (and we are in 2020) It is not a problem with LyX itself: if you stick to 100% compatibility with LaTeX then there is no much more you can do.
