 ## Roadmap
 
-- [ ] cleanup UI code (this is a bit of a mess)
-  - add different display modes (`mtr` features different views)
-  - properly align colums to use the full terminal width
-  - drop columns, when screen is to small
-  - move "last error" column into a log area at the bottom
-  - increase/decrease interval and/or timeout with `-`/`+` keys
-- [ ] fill IPv6 options with life (once the library has IPv6 support)
-- [ ] use something more sophisticated than `net.ResolveIPAddress` to
