A couple of new categories for the site!
Today someone actually registered on the Tracker.BootBlock.co.uk site for the first time, and as a bonus, they even created a nicely detailed bug report.
So I began working on fixing the bug in FileSieve (specifically, a plugin) and instead got side-tracked and added a preset set of filters for removing invalid OS characters from filenames.
Next up will be to add low-level support for removing/replacing invalid characters rather than shoving it into a plugin, and fixing the reported bug.
Edit: The date grouping issue on this site doesn't look like it has been fully resolved.
