People do have that attitude from time to time, in this case i'd phrase it more like "no one seems to use their computer the way i want to, so i wrote some software"
Firstly you insinuate that the author is requiring people to interact as they do - this evidently is not the case, a suggestion has even been made on one of many ways to behave differently.
Secondly the "I seem to be getting along fine without it" statement pointlessly hampers progress. There is no basis or reasoning for this, instead there is a decision - whimsical by the looks of it - to not use it. You could say that you don't anticipate the gains of the system to be worth the transition cost, or you could actually try it and have some useful criticism, or any number of other things.
Thirdly, the linked page doesn't ever mention the 'minimal' your parent introduces. Minimal implies sufficiency (least sufficient, but sufficient none the less), the Alacritty page states simple - which does not.
I find the final comment hilarious. You have just denounced a tool based on an implementation triviality (which can be easily bypassed) and choose to summarise with a statement as undoubtedly false as it is trite. Did you read the page?
I'm sorry if I came across as overly critical of the project, that wasn't my intent. I just think they're limiting their audience by assuming that a feature that isn't important to the developers is unimportant to users because a workaround exists that the developers are satisfied with. People really don't like to change how they do things, regardless of whether the way they're doing them now is "the right way" or "the best way". Maybe they're making the right decision and everyone really should be using tmux, and if so, great, they'll have have a community of happy users. If their target audience is someone other than me, I'm okay with that.
> Features like GUI-based configuration, tabs and scrollback are unnecessary. The latter features are better provided by a terminal multiplexer like tmux.
This seems kind of like saying "everyone should use their computer the same way I do". I don't use tmux; maybe I should learn to use it. However, I seem to be getting along fine without it, and no scroll back is a deal-breaker for me.
That said, this is still a cool project and I wish them success.
