Minor workflow suggestion for entering time logs:
I tend to look at the calendar view of my time logs to see where the gaps are, it would be great if I could right click on a day in the calendar (which currently brings up a context menu with only 'Configure' in it) and quick-pick from my tasks to start an entry. Currently I look at the calendar view, write down the dates I'm missing, then switch to the tasks page and click the plus buttons next to my tasks to make the entries.
Also, it would be great if you could enter a default description against each of your tasks, as it's quite common for large groups of people to just enter a generic task there (i.e. 'supervision' for me).
