I was inspired by the amazing Mac app Boop and decided to make a NeoVim alternative.
This plugin is a result of my attempts and it works really good. It uses Telescope or vim.ui.select() to pick commands. Then it uses entire buffer content as an input to the chosen command. After running the command, the buffer content is replaced with the result of the command.
There was also an announcement on Reddit, which gave a me a few ideas to improve the plugin.
