As of 8.5.0, the GUI now picks the default job log file to display based on the task state:

- failed → job.err
- submit-failed → job-activity.log
- otherwise → job.out

This speeds up the loading of the log file because the GUI doesn’t have to wait for a listing of available log files before picking one to view.

Additionally, the log view now has an auto scroll feature which follows the end of the file (useful for viewing the file whilst it is being written), and a scroll-to-top button.
