- Paste photos onto an event without opening it....
- copy paste pics after performing a search... it has to be from the main 'unsearched' view...
- split/merge or basically do ANYTHING after I searched for photos... WHY the hell does iphoto care if I searched for it first? erggggg....!!!
- have a Sub-event of some sort...
- and so if you cut/copy a picture from one event you have to scorll/while clicking until you happen to stumble upon the event you're looking for...
- and so many other things I can't think of at the moment...
I have approx 18,000 pics.
It just isn't flexible enough !!!

I thought I was going to like it, and I did at first - but not anymore!!!
Here's my take on events and folders/albums in iPhoto:
The interface is not perfect. I agree, events should be easier to manage in, and there should be sub-events. However, no matter how much iPhoto talks about events, the real power is in albums and folders. Just remember: albums contain photos, and folders contain albums (or sub-folders). So, you can create three albums under folder a, three albums under folder b, and folder c can contain folders a and b, and also another album.
Aperture's folder and project support is much more robust than iPhoto's, but I actually like iPhotos overall user interface quicker and easier.
Some suggestions to get started:
Try right clicking on events, and choose "open in new window" then you get a floating window of the event you want to disperse photos from. Type "apple-~" (apple key plus the tilde key) to switch between the floating event and the main iPhoto window.
I am not sure about copy and paste from search, but here's a tip: I only use flags on photos for short term organization. As I look through my photos to group them together, when I find one I like, I hit apple-. (apple key and the period key). This toggles the flag on the photo. Once I have flagged all the ones I want -- look on the left and you'll see a folder called "flagged photos" That now contains a reference to all the photos you just flagged. You can then open this folder, type "ctrl-a" to select all the photos, then drag those photos into a new album. When you are done, select all the photos in the flagged folder, and type apple-period again, and that will unflag all the photos, and empty the flagged folder, and you can start over with a new grouping. I'll have to get to my Mac and check out how to use this when searching.
One thing you may be having trouble with is events vs. albums. Events contain your "original" photo while albums contain points to that photo. So, you can only have a single photo in a single event (unless you duplicate the photo). However, you can have that same photo in multiple albums, because it's only a pointer. For this reason, the copy and past behavior between events and albums is different.
One other tip to try -- in preferences set double-click to "edit picture" and set edit to "edit in full screen" This opens the iPhoto editor every time you double click a photo. Then when in full screen edit mode, go up to the view menu, and set thumbnails to be on top (for example) and hide. This is just my preference, but I think it sets up a pretty cool interface for working with your pictures.
Other tips, when in full screen edit mode -- type "A" to open adjustments, apple-I to bring up the information screen (and vice versa for to close either one). Also, use "c" for crop and "s" for straighten.
Sorry for the random ramblings. It's tough to explain this on-line. Feel free to PM me with specific questions, and I'll be happy to help.
