There is a lot of system filters that are not relevant for custom projects and must be edited or hidden so there is much better user experience and the user is off the mess.
I would like to have editable the system filter defintion:

Pelase if you see this very good suggestion could you vote for it so it can be implemented? Just now there are suggestion with only 155 votes and it is very little. We need more than 1500. Thank you for voting for getting up jira user experience.
