Hardtime.nvim is a plugin designed to help users break poor habits when using Vim, encouraging mastery of motion commands without offering hints. This enhances instinctual navigation capabilities over time. Users have shared a mix of enthusiasm and constructive feedback about its effectiveness, detailing their long-term experiences with Vim and how the plugin has either challenged or engaged them in improving their skills. The plugin also appears to inspire thoughts of expanding its use into other editors and functionalities, indicating a broader desire for enhanced command optimization in various coding environments. Users appreciate the concept of a 'Hardtime Report' that tracks bad habits, although there's a call for compatibility with Vim given some users' hesitation to fully switch to Neovim.
