Thanks for your kind words. That column feature is really a little complicated, but what it does is, too.
Regarding your suggestions, if you want to have a feature you can open a feature request ticket for it on the trac, too. We then will add that request to our poll to see what general interesst is existing (to plan our resources).
But anyway a few statements to your suggestions (my fellow developers may see some things different...:-)):
[i]nother thing I'd like to see is a separation of files in the templates exactly like wordpress does, with separate files for header, footer, albums, images, and maybe sub-albums why not? That way i don't have to edit each file every time... Of course i could do php includes but i noticed it slows a bit when used (maybe i did something wrong).[/i]
You can organize your theme any way you like. You have the absolute freedom to modify your theme that way.
By the way, Wordpress uses php includes and I would not know how to do it differently (which does not slow down BTW)...:-)
[i]- Tagging right in pictures with layers (like facebook)[/i]
I don't know or use facebook, so I neither know what that is nor what this is for. Is it the same as the flickr notes? A user made something up for that: http://www.zenphoto.org/support/topic.php?id=2372&replies=10
- Visitors can tag images (with approval option), and relative template function that lets you show/hide tags from users along with tags from admin.
I personally have never thought about that. Please open a ticket.
[i]- Javascript lightbox zooming of image[/i]
Lightbox is easy to implement with in a theme and will never be a core feature itself (BTW, thickbox js is included in zenphoto). It has been done numerous times (I believe there is already a theme with it). Please do a forum search on that.
[i]- Editing of templates directly from admin (like wordpress), with a list of functions available to copy paste directly. This makes it very easy for everyone to edit/add features without no html requirements. It's like a "copy-this-code-to-your-website-to-show-image" you find in facebook and myspace.[/i]
Editing templates is already on our poll, so head over and vote for that feature...:-)
[i]- Simple stats (Very simple).[/i]
What exactly do you mean? We have a bunch of functions for archive, latest, most voted, top voted, most viewed images.
[i]- Album rss feed (not image) [/i]
Do you mean a feed that shows the latest added albums?
