## Description

Grading automation actions.

Key features of the program:

Instant column copying: Allows you to copy grades from one column to another in a single click (for example, transferring marks from the "Notebook" or "Quiz" column to the thematic or current grade column). No more manual transferring of every single grade for each student one by one.

Quick data clearing: Allows you to instantly delete all grades from a selected column if an error occurs or if the page needs to be filled out again.

Automatic column numbering: The program automatically numbers all columns of the gradebook directly in the table header (for example, [3], [4], [5]). Teachers no more need to count columns with a finger on the screen — simply look at the blue index above the date.

Flexible delay (timeout) configuration: If the <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/d6b71d7233368db569338689dd3614e28012c4b504efd5e01e1ba1cc57268be8/http%3A//nz.ua" rel="nofollow">nz.ua</a> server is overloaded and starts to lag, you can increase the delay between requests (in seconds) directly on the panel.
