For example, in my [[ https://logstash.wikimedia.org/app/kibana#/dashboard/6bcd2a10-7d21-11e7-86fb-51c84229aeb7 | network dashboard ]] I used the "[[ https://logstash.wikimedia.org/app/kibana#/visualize/edit/Top-Hosts-table | Top Hosts table ]]" visualization.
Recently, someone edited the "Top Hosts" to filter on `type:"mediawiki"`, which caused my dashboard to break.
So I think it would be great to have a naming or usage convention for visualizations as they can be re-used.
For example we can decide that each visualization need to be unique per user/team/dahboard, to avoid people like me to re-use existing visualization.
Or if we encourage re-use, maybe the generic (# no filter) viz should have a generic name, and as soon as customization is applied, rename the filter or create a new one (it would be useful here to be able to know where a visualization is used too).
