If you want to break out of the windows mold, tiling windows managers are where its at. You’ve already explored that route with i3, and there are other alternatives, but they all have a bit of a learning curve unfortunately. hyprland might be worth a try. I’ve only dabbled but I did remember it being a bit more beginner friendly than i3. But be prepared to be confused, read a bunch of forum posts and edit config files for a bit.

The biggest thing missing from helix right now imo is plugin support, so a lot of plugins that I really like wouldn’t be available. I use fugitive a lot for working with git for example.

Another one is the quickfix list in combination with ex commands. One thing you can do for example is setup :make to run your compiler and then when you get compilation errors they’ll show up in your quickfix list. You can then use :Cfilter to focus on one type of error and then :cdo to for example do a find and replace on the remaining lines.

In general, if I don’t have an lsp available for whatever reason (I work in cmake a fair amount at my $DAYJOB for example) I would much rather use vim, in particular because of the stuff that you can do with ex commands that I mentioned above (also works great with grep) but also because of the ctags support.

Helix can do a lot of nice things out of the box for a lot of cases of software editing, but it’s not nearly as broad or as customizable of a tool as vim

Vim still has a lot of advantages over helix. Being modern doesn’t automatically make a tool better
