Review Summary
Found 1 issue in the changed code that should be addressed:
High Severity
- Negative maxDescWidth when terminal width is very small: The calculation on line 64 can produce negative values when
c.width < prefixWidth, causing word wrapping to be completely bypassed.
The word wrapping logic itself looks good for normal cases, but needs defensive handling for edge cases where the component width becomes smaller than the icon prefix width.
Replace truncation with word-aware wrapping so that todo items in the sidebar display their full description regardless of sidebar width. Long descriptions wrap onto subsequent lines, indented to align with the text after the icon prefix, and line breaks prefer word boundaries over splitting mid-word.

maybe we could also add some minimal visual separation between the todos 🤔 will give it a look

Adding separation will make it even more vertical, idk |

true, but maybe even todos should have a title and content if they are that long though, these in the example are more like full blown tasks than simple todos.. but anyway stuff for separate PRs |
