stepan , 1 month ago I also tried https://github.com/smoka7/multicursors.nvim and the experience was horrible. Then I tried https://github.com/brenton-leighton/multiple-cursors.nvim and I absolutely love it. It has conflict with cmp, but the README has great tutorial on disabling cmp only when using multiple cursors, and dealing with other plugins to maks them work or disable them in the multicursor mode.
