Does Helix have no way to go back to the last editing position when re-opening a file? Similar to: '" in vim? That is going to be a deal-breaker for me. One reason I use vim over many other options is that I jump in and out of files a lot, having to find my last position in many cases is a chore.
If you don't have one already, here's an autocmd I use for that https://gist.github.com/shorsher/93b747bf5c4209f45ef0304aa50...
I gave helix a serious shot for a week, converting shortcuts and adapting to helix's way. In the end I couldn't find any advantage to it over my vim setup. It was not plug and play it was not configuration free, it was not noticeably faster. It was just full of negatives. Little gripes like the one you mention. Vim just seems to do everything better with fewer popups and selection flashes.
