 ## Why did you write this instead of improving timetrap?
 
-* timetrap is hard to install, hard to keep updated (because of ruby). Once this

 ### Other advantages
 
-* Columns are always aligned
-* Fixed some input inconsistencies
-* cli interface is much better (ask -h for any command)
-* man page (to do)
+* Columns in the output are always aligned.
