logging / entering daily textual description of work completed, along with hours

I've been exploring the software for only a little over a day (I am familiar with other similar ones, e.g. Odoo, ]po[, openproject, erpnext) so I hope this isn't too premature to ask. I've searched with search engines, the manual & index, and here in the forum for things like "daily work description text" and found no luck. I have completed the 'checklist' on the home page and have several Users, Contacts, Projects, Activities, and Timesheet entries already.

Question:
As Activities are often many days long, is there a way of (say at the end of the day) entering a Resource's (e.g. employee's) time *along with* a short textual description of what was done that day?

It seems the Diary is generated ("planning driven"), Notes are germane for the length of the task, and I don't think Tickets are appropriate. I have not found anything by either logging in with roles of Admin or Project Manager.

(quite ugly):
I could add a note to the Activity, and then change it every day so that a record is kept in the Change History...
I could have each Activity only last a day and then the Description field would be applicable only for that day...

Kind regards,
Brett

I am looking for the timesheet but its not listed in the menu default. Where can I find the plugin for it please? I need to be able to have the employees time logged that they started and ended each day they work.

Would you know the url for the plugin please?
