a minimum timer easy to use and integrate

I work at the moment  on simple and easy to use tools.
Here is a  proposition for a compact and easy to use and integrate timer with all the functions I was searching during performance creation.
In my github, there is the TOX and a short PDF manual.
Waiting for your feedback,
