Genuinely awesome project - especially fit 'n finish. I have a happy place in my heart for this style of terminal app (TUI++).
I hate to ask this, but do you have any plans for implementing modal editing or vi-style shortcuts? EDIT: I feel so guilty asking this question, that I realized that a second "Alternative Shortcut" field would go a long way for me as well. No expectation that this would be implemented, just sharing my thoughts.
More importantly though: awesome project that I do plan on using for my personal writing project (nonfiction book) and at work.
