Tried to get things done 
.
I will try to make a pull request today to upload my modifications.
The features so far:
- add details to the job summary, not the main progress bar
- added a mini progress bar for file processing
- active / stopped jobs are indicated by different icons (thx to @kees-z, I modified them slightly…)
- details only visible while processing files. While deleting, upload and backend-action ect. these details are hidden
And a screenshot too:
Some cosmetic / html modification is required (help needed…) but I think maybe we can start with this one?..
ToDo: integrate translation of the new infos: current action, progress, current file
