Feature Request: Add description field in records

Hi

I want to submit a fetaure request. I know it has already been touched in #115 but at the end only tags were implemented.

I would love to have descriptions to the records timetrace creates. I"m also willing to contribute code to this project to make that happen.

Let me know if you are already working on this, or else I'll take up the task.

BR and thanks for this wonderful project!
