Speaking of zed, if the team at zed is reading this, then I genuinely believe with my full heart that you guys can actually solve this issue given the impressive work you have done at trying to make the editor fast.
If you work towards something like google docs etc., this product feels right within your category and can work with the team features at zed to a far greater degree.
Zed also natively has AI functionality so it can work for some people and the best part about Zed is that AI functionality can be toggled off too :-)
This might as well be a billion dollar unsolved problem which the team at zed could use their expertise on perhaps. Although I suggest that maybe instead of bolting these functionalities into zed itself, maybe a zed-fork can be created for a more Microsoft word alternative?
Has someone tried at making a zed extension which can somehow be a word editor or anything similar, perhaps it might be possible within the frameworks of zed now itself but I am not sure.
I hope someone at zed team reads this and solves this problem. Zed is fantastic piece of software, thanks for making it zed team :-)
