Great addition. The only suggestion - perhaps some css class or "new" label next to a freshly added file. When adding another file to a already long list, the latest addition might get unnotified. A Drupal Fade Technique? ;) http://www.axentric.com/posts/default/7
Yeah I wasn't sure if we wanted something like that here: the new file entry shows up where the file form and progressbar was. The visual link is quite clear. Implementing a generic Yellow-Fade-Technique in Drupal is also tricky because you need to deal with the page cache.
hm, quite an interesting UI concept to mix classic "progressing" bar and "endless loop" bar. I'd still keep those separate. Also, the progress % is hard to read on animated background
The percentage should be above the bar, not in it... you're probably seeing some clearing issue with my theme. Because it will be monitoring the progress through Ajax, it will not update very smoothly, so a constant animation is not a bad idea. Thanks for the review, Steven Wittens
