Contributions summary:Jakob primarily focused on improving the functionality of the `lazygit` terminal UI. They implemented features to remember commit messages when commits fail, refactored and renamed variables, and added tests to ensure the commit message persistence worked correctly. The user also modified existing code to handle commit confirmations and error states, improving the overall user experience. Furthermore, the user made a minor adjustment by removing a redundant commit.
