Please take a look at Kimai for some inspiration on how to implement Phrequent. It is very clean and simple and easy to select, start, and stop timing events. Phrequent also needs the ability to track against more than just tasks. For example, our organization would use it to track time against support calls, etc.

Maybe it should better be worded that while using the product I keep finding myself removed from the context I was working in and have to move all the way back to home and start over. For example, when in a project board, now create a new task. You are removed from any project context and you create the task. When done creating the task you have to go back to home, select projects, select the project and get back to the board.
