A couple points of feedback:
- As a person who lives anywhere but the US, the date format is all wrong and will constantly be a source of annoyance. The datepicker helps, but the csv outputs dates like 07/08/14... I have no idea what date that is. How about ISO standards? 2014/07/08 is completely unambiguous to everyone.
- I often do a whole day of work. Say like 4+ hours for a single client. I write a lot of notes during that time for my own reference. So I really need to be able to: type notes while the timer is going, and also for the notes to respect my line breaks (otherwise it just comes out jibberish if I try to write bullet points/etc).
- I guess I will use the submitted->approved flow for pending->billed. Not sure if this is something you intend... I 'approve' my own hours, but I would like to be able to mark hours as having been billed so I don't accidentally do it twice :)
- The little bubble next to my entries says 'RF', I assume that's a place for an avatar. Am I blind and missing how to set one?
But yea overall it looks great!
