Improve the site on Codeigniter

There is a website on Codeigniter for training company employees.
Different functional modules have been implemented on the site, within the framework of this project, the "Goal-setting" module needs to be improved.

The meaning of the module is that a user with the "Administrator" role assigns various text goals to employees, and employees fulfill them and coordinate their implementation with their manager.

The module itself has already been implemented, but some of its functionality needs to be adjusted, for example:

- Remove the limit on the number of characters entered in a certain field
- Lock the "Save" button on some forms, because double-clicking it causes the creation of two objects
- On the procedure page, display more information about the employee (now only the full name and email are displayed, and you also need to display his manager and department)

etc

All tasks are quite small, but there are a lot of them (several dozen) and they will definitely be immediately clear, without a long immersion in the project. I will send a complete list of tasks to the selected performer.
