Consequently it should work in all text views, text fields, search fields and the text entry line of combo boxes. The completion facility gets its information from the spell checker. While we're talking about the not so well known/hidden new Panther features: while digging through the kernel sources i've found a quite amusing new feature built into HFS+. Namely automatic file defragmentation. Everytime an application opens a file for reading, HFS+ checks if the file is fragmented and is less than 20MB in size. If so, it copies the file's contents to a continuous region on the disk and frees up the previously allocated blocks. HFS+ now also supports more efficient file searching. I.e. an application can tell the FS that it should ignore the contents of packages/bundles. Another interesting thing is that the VFS layer now supports file system notifications for some operations. Examples are: free space on a disk has fallen under a certain threshold (50MB for root disks) or a new file system got mounted or unmounted. Hmm, anyone still remember the discussion we had some months ago about how a process which runs out of swap space can screw up the file system ? Looks like Panther should behave more rationally under this circumstance, because the VM will now put a process to sleep if it takes a page fault and the backing store has become too large.
