For agents that don't need precise time tracking but need something simpler than a pop-up with manual time entry it would be great to have 15, 30 or 60 minute plus "+" or minus "-" buttons that simply adjust time per click. Something like this:
[ Time tracking ]
- 15 minutes +
- 30 minutes +
- 60 minutes +
Using a keyboard you could Tab to it and click left and right arrows.
The current system requires expanding the time track section ( 1 click ), clicking add time ( 1 click ) interacting with a pop up, manual entry of time ( 5 taps of keyboard ) then clicking 'save' ( 1 click ). Wouldn't it be better to have it directly under categories and all you need to press is + and - ?
