Actually, even API is not thought-through at the moment. For instance,
(BOOL) imageBrowser:(IKImageBrowserView *) aBrowser
moveItemsAtIndexes: (NSIndexSet *)indexes toIndex:
(NSUInteger)destinationIndex;
of IKImageBrowserDataSource only specifies destination index. This
API breaks at the group boundary: destination index at the end of one
group is just the same as beginning of another, and you have no way of
knowing which one it actually was.
In fact, call me old-fashion, but I hate IKImageBrowserDataSource
design altogether. As far as API goes, I would ask from data source
group list, and for each group - item list. Internally, they could
construct global item array, etc, but to expose well-performing
structures as provider API is simply bad taste in my opinion (and very
70-ies too ;)).
Hope they'll fix it one day...

Just a heads-up in case anyone else is wondering about this: There
seems to be a bug in IKImageBrowserView -- namely, at least these
two methods are missing:
--
- (void)collapseGroupAtIndex:(NSUInteger)index {
[self collapseGroup:[[[self layoutManager] groups]
objectAtIndex:index]];
}
- (void)expandGroupAtIndex:(NSUInteger)index {
[self expandGroup:[[[self layoutManager] groups]
objectAtIndex:index]];
}

Mind you: They _are_ in the header files, but apparently, they are
just not implemented. I managed to simulate them after learning
about the inner workings of IKImageBrowserView via class-dump.
Cheers,
Peter.
