Update layout of Worklog entry and tab order

I rarely need to modify the Log time and time spent when creating a worklog, so was wondering if they could be grouped together, and moved to the end of the tab order?

If the Tab Order can be set however you need it, regardless of where the fields are, then I could see these two fields at the top, but the Ticket no field is the first in tab order, so you could shift+tab to get back to these fields, if needed.

Additionally, it would be nice if the Ticket no field could be the default field with focus when Worklog form is displayed so you can immediately start typing, then tab once to get to and enter comments, and then tab once again to get to save button.
