Is your feature request related to a problem? Please describe.
When I use the application, I often:
- Forget to start tracking an activity
- Wish I had started one
It is annoying having to go meddling with time ranges retroactively.
Describe the solution you'd like
I want to be able to give A Time Tracker an open-ended range. That is to say, I want to be able to "add a time range" with a starting time but no end time so that it will be as if I had remembered to track the project.
