New token?

I’m interested in keeping track of how long I take to finish a job.

Would it be difficult to create a token which shows the total duration that a project is open? Is there another/better way?!

How about an ordinary task./project timer app? What happens if you leave Dorico open for an hour while you go to lunch? Is this for charging clients?

Well, I’d have to close the project for it to work. I guess if I have to remember to close the project then I can remember to write a time down. Yes, it is for working out fees etc.

Take a look at Clockify.

A much more fully fledged client billing timer.
