Description
When creating a new file for rules or decoders you can only save once before having to exit and reopen the file.

Steps to reproduce

1. Go to Management > Ruleset
2. Click on Manage rule files
3. Click on Add new rules file
4. Give a filename and content to the file
5. Save
6. Make any other change
7. Save again
8. Receive "FILE NAME ALREADY EXISTS" error
9. Notice changes are not saved.

Additional context
A prompt to overwrite would be a lot more user friendly , otherwise you must go back out to Rules after the first save, select "Manage rule files", toggle "Editable files" and then continue editing there.

Now, when we create a file for rules or decoders, it automatically takes us to edit it, thus eliminating the problem of overwriting files:

Rules:

Decoders:
