These are more feature requests than questions.
Why is it not possible to rename a saved search?
I have too clone it to change the name.
I'm stuck having to name my searches according to relevance.
Would be neat to have a folder like structure.
Are there any plugins(addons) to group and rename saved searches in the "Searches and reports" section?
This gets a little unwieldy I think when we start to introduce multiple search heads, and when the person wanting to rename the search is not the same person who has administrative, command-line access to the search head servers.
If there is a place to upvote feature requests, like the ability to rename saved searches, just let me know.
Is there any update on this being added as an Enhancement or is there an easier way to rename searches than this? I have admin access to Splunk but not access to our Splunk server so editing a .conf file is totally out for me.
Firstly it is possible to directly edit the names of scheduled searches, have a look here at the config. If you edit the config directly it will require a restart though so you may find it doesn't have a huge amount of time.
I believe the feature to change the name of saved searches is already an ER (enhancement request) but it might be worth submitting it anyway just incase ->http://www.splunk.com/index.php/submit_issue
As for plugins etc to group saved searches, why not build an App?
If you haven't really looked at Apps before they are briefly best referred to as work spaces. An App can be nothing more than a collection of custom dashboards, although you find alot of Apps for specific purposes its simply because people have taken the time to extend functionality.
You could create an App for each "group", that way you keep similar savedsearches and related dashboards together. Click here for more info about Apps
Restarting splunk is not required.
It is enough to refresh the config.
