At a glance, only annoying things (so far) are the illegible hidden file names (really blurry) and no Markdown or other previews. Icons are also really plain which makes finding files a bit harder as everything looks the same. And no icons for extensions either? Feels a bit too brutalist, even. Seems default keymaps are quite similar.
But the performance is there. I'm not sure will I switch now but I will definitely keep coming back to it.
