I have been using Zapier successfully to implement Airtable to Airtable automations (creating records for multiple customers etc) for a client and I have come across a case where it would be fantastic if there were a Find Records (Plural) which would return a comma separated string of record IDs (or even better an array of objects) which could be used in subsequent Zapier steps to do some process on all records.
Mentioning the Array of Objects above, I have had to write Javascript in Zapier to convert the strings you return from linked fields into these - it would neat to have an option for the step to return these as arrays of objects instead to remove the need for this in some cases.
