Answer to question 2:
- Go to the list -> List tab on the top ribbon -> Workflow settings -> Create a Workflow in SharePoint Designer.
- Add a name to the workflow -> ok.
- Change the settings to start only when an item is changed.
- Add an action "Update list item" -> Click on "this list"
- Select "List: Current Item" -> Click Add
- In the "Set this field:" select your title column; in the "To this value:" click on "..."
- In the String Builder dialog window click "Add or Change Lookup"
- Data source: current item; Field from source: your title column -> Ok
- It will look like this: [%Current Item:Title%]
- Add space and *
- Click Ok -> Publish the workflow
- Done! :)
Now when an item in this list get changed, "*" will be appended to the end of the Title column (or other column you specify).
