For example, the italian holidays ics file now it is changed (for bug fixing, see bug https://bugzilla.mozilla.org/show_bug.cgi?id=471807). It is a good chance if I can delete all previuous events of "holidays" category before re-import new file. Reproducible: Always
Already possible: Enable "Find Events", search for the category name or sort by category column, select all events and delete them.
Reasonable workaround possible, closing bug.
