Re: Controlling Page-Level access in App Studio
You'll need two different apps currently. I'd recommend logging an idea in the idea exchange to allow for more granular app page level access.
Re: How to identify workflow initiator
Jaden was quick in the response, thank you Jaden!
John, thanks for backing up my feedback to the team that this should be a "system variable" that just exists for every workflow…who started it, what time, how, etc…
Re: SELECT ALL in dropdown filter
It is allowed in other places, seems like a bug that it does not work the same everywhere. Getting this fixed would improve my user's experience. Thank you!!

Re: Period Over Period Charts
This would be great! An increasing number of my dashboard users are asking for the ability to have the period over period comparison be flexible with the top level date filter of the app/dashboard.
Adding to what @ggenovese said, the current solution (linked at bottom) of beast modes and additional ETL are not scalable. Providing more options to end users results in duplicate records. Beyond duplication of metrics it duplicates row counts. You can use views to reduce row credit consumption, but this quickly slows down dashboards/apps as cards are slower when powered by views.
Potential solution could be a conditional drop down in the top level date filter that enables changing comparison periods. If PoP cards are present on dashboard/app, then show "compare to" option. Additionally, dashboard/app editors would have the option to show or hide this conditional drop down.
Example: PoP cards on an app are default are set to current month-to-date, compare to one month ago. When the user changes the top level date filter to yesterday, all of the PoP charts compare to the same day one month ago (I believe this functionality is already in place). The user could then change the "compare to" filter to "Day over Day" and all the PoP charts will update to compare yesterday to the day before.
Hope this explanation helps and looking forward to enhanced PoP cards!

Re: Conditional Gateway Tile
A team member of mine reminded me that you can do this using the error function in Magic ETL
Re: Querying workflow task on task completion
Good stuff. Glad you got it up and running.
Re: Can the Bar Total Label be the Total % of the bar instead of the integer?
I think instead of bringing in the total and selecting the 'percent_of_total' label, you'd need to calculate the percent of total first, and use that as the value. Then your totals would appear correctly.
Re: App Studio - Allow more than one user to edit at a time
This would be a game-changer enhancement to App Studio! I constantly am working on projects with teammates where we are working on the same app. Allowing for multiple people to make edits at the same time would be tremendously helpful.
Re: Control variable options that are populated by a dataset field or copy and paste
Note: I've used Tableau and Looker in the past, and both had the option to copy and paste rows from spreadsheets into filters, dropdowns, etc! Would love to see Domo add this feature as it saves an incredible amount of time.

Re: Control variable options that are populated by a dataset field or copy and paste
Yes! This would be great!
