We use the version number in app.conf for version control of Splunk apps. I know you can directly edit the app.conf file and update the version number. Is there a way through the GUI to update this value? I saw for an app that you can edit properties which does an action=edit. Is there a way to customize this to include the version number?
Possible, but not recommended. It might break when you upgrade (move to the local folder for the app just in case). That being said:
In the file $SPLUNK_HOME/etc/apps/search/default/data/ui/manager/apps_local.xml, locate the section for "Version". Add this into the list (in between list and create): <view name="edit"/>. This will work for any other properties as well.
