MacVim and gVim. I've looked at neovim and there are many GUI options (paradox of choice), some of which I've tried, but at the end of the day, I'm more comfortable with what I'm already familiar with.
Likewise. I’m a heavy CLI user but gVim/MacVim are so entrenched in my workflow that the lack of a stable GUI for Neovim made it pretty much a nonstarter for me.
As some one who only uses vim/neovim in a terminal window - what’s the advantage of having GUI support in vim?
Mouse support in my terminal seems fine, even over ssh. Being able to do things like run it inside of a tmux session has always made it seem like the GUI would be a step back?
You can use gVim as a Notepad on steroids. You have the simplicity and familiarity of Notepad combined with the power vim, e.g. search & replace using regular expressions, syntax highlighting, the ability to delete 5 words by typing ESC d 5 w, plugins like fugitive and so on. I can't select text in neovim by pressing Shift and arrow keys. I can't copy text by pressing Ctrl+C.
I did the Vim -> NeoVim switch a while back (pre-vim9script) and lack of standardized GUI is a non trivial issue. There are solution(s) - but allof them have had too much friction to fit in a workflow for me. Definitely a concern.
