add timestamp on comments

I am evaluating your product. It covers all my needs except two. for every todo item, I do a detailed follow-up of its progress. I do this by adding text to comment on a regular basis. example:

task: arrange appointment with plumber
comment:
16/12 17:00 called him. no answer
17/12 12:00 his wife answers. left a message
18/12 08:30 called back since he didn't answer. arranged appointment for next friday

To do his I have to add the timestamp (date and time) manually each time. It would be very helpful to have an automatic timestamp.

Secondly, I'd like to have a shortcut key to save a comment (f.e. ctrl-enter) in order to avoid having to click on the save icon.

You can use F5 key for time stamping
