Proposal
Having a setting which shows a notification when a certain threshold is reached would be a nice addition to the desktop app.
Use case
I work flexible hours. I usually have a 2 hour window in which I enter work. I log every single minute in Toggl and therefore use it to track my total work time.
A simple reminder when I finished tracking my 8 hour workday would be nice. Since this is dynamic in my case I always end up losing myself in my tasks and therefore lose track of time.
Toggl could help me get home in time!
Possible workarounds
If Toggl Goals had an options for when a goal is reach this would suffice for my use case.
