Version: unspecified (using KDE 4.5.0)
In the interface to select which links from a list that you want to download, it is possible to filter by specific file types or by wildcards. I think it would be nice if there was also an option to filter by regular expression (regex). It would probably use the "filter files here" box.
Perhaps there could be regex checkbox, but that would increase the size of that row substantially. Another option would be to change the contains/does not contain dropdown to a menu button (a button that triggers a menu), with a pair of exclusive (radio button) menu entries to switch between "contains" and "does not contain", and separated by a divider a checkbox to enable/disable regex mode.
Reproducible: Didn't try
