Looks like the popups preference (which is also now the joint preference) is a already being tracked.

Page Previews doesn't appear to make use of OOUI so adjusting the settings popup to match/use OOUI elements should be done in a separate task.

TemplateWizard Grafana board doesn't exist yet so it seems appropriate to implement this from the get go in T270239

Open questions:

What is the purpose of the filters for parameter action and template action at the top? Selecting any of the options doesn't seem to change any of the charts for me and I'm not sure this is useful as the actions are represented in their own charts below.

Also it seems like you changed the way that the percentage of dialog sessions when {some action} is performed are displayed, but something seems off. This is how they all look to me:

Maybe this has to do with breaking down by wiki? If so, I think this can be combined - for example, of all dialog sessions on all wikis, the description was changed 10% of the time.

• Adding a readable graph for average of data for all wikis, showing percentage of sessions where action happens, per action

Done

• Updating percentage data with 'speedometer' graph to communicate percentage-ness

Done

Hey @Andrew-WMDE thanks for sharing the board for review. I have a few questions, some which came out of the discussions about the CodeMirror board and some which are related to just TemplateData.

General

• I think I caught a small typo: fr should be fa for Farsi, instead of French (unless it's actually collecting data from fr.wikipedia?)

I see various interpretations for the "Authors" column, I, for one, interpret it more as a credits list than a list of maintainers. Therefore, I would expect that we first ask the listed individuals whether or not they want their name removed.
