We use Jira for project planning. Jira is nice — because it has swimlanes and also nice commenting fields... But it is horrendous to do time and budget planning, estimation and follow-ups.
Current Jira is used for TODOS and project tasks. Then — I hold my breath and COPY EVERYTHING OVER TO AIRTABLE. Having everything in Airtable lallows aggregations, lookups, rollups and all the other magical stuff that makes Airtable so nice.
So, now I am waiting. And waiting. And waiting some more. I need Airtable to implement swimlanes. It is insane that they haven't already done so. I cannot see a future where they haven't. That would bring new customers.
When they do, Jira is history (for us).
