---------------------------------------
Hi [~twinkle],
I think the UI on the latest screenshot is a little too cluttered. How about:
- Keep the app id as the main link to the application's UI, pointing at the
last attempt in the case of multiple attempts
- Have the attempt column list the attempt IDs only for those apps that have
multiple attempts. Those with a single attempt would have an empty cell.
This would result in a redundant link (app id link + link to the last attempt
pointing at the same place), but I think it looks better. And it's probably
less confusing for those used to the current UI.

> The even log path should be "more unique". Or perhaps retries of the same app
> should clean up the old logs first.
