I would like to display customer pages completly in a different language. This is important for international sales or non-US local business

A huge step in the right direction with the newest update is packages. The customer can select different images for the prints in the package. How about taking it one step further and start offering albums. It seems to me like it would work like package, except instead of the customer picking prints, they can be pages.
I know a lot of users have been asking for albums, so please give this one some votes.

Having only 8 layout options is a bit inconvenient. It would be awesome if there were a customized layout option, or better yet a tool to BUILD your own layout by drag/drop specific elements onto your page.

the ability to have clients schedule and pay session fees though Zenfolio would be very useful. the paypal integration is there, so just some sort of scheduling plug-in

Support for upload of RAW/DNG files directly.

the iphone app we have today is amazing, however it is for members of Zenfolio. We need an iphone app to give to clients, give them a quick client access code, and the iphone app shows just their photos.

My biggest complaint about Zen is that the homepages are great--if you like one of the few standard layouts. But, these layouts are all somewhat similar and feel quite dated. Newer, more modern layouts are needed badly! And not just for the home page--which is more important, but the galleries need some sprucing up as well.

Currently the most popular Photos / Galleries leaves a lot to be desired. At the very least make it the top 10 most popular photos - but preferably have the chance to drill down on a per gallery basis. I know Google Analytics exists - but I'm not sure why we should need to sign up to an additional external account to find out info on our shots.

It would be far better to have emails sent from my domain than "Zenfolio [noreply@zenfoliomail.com]; on behalf of; CCG Creative Studios, LLC [sales@ccgcreativestudios.com]". This is simply not a very attractive presentation to the client. You've done a very nice job removing branding in most places for the Premium account, but this is a weak spot.

If Google Mail can figure out how to send email through my SMTP server by letting me set up credentials in the proper way, then surely the smart people at Zenfolio can find a way to do the same thing.

If you would like to have a Calendar Based Booking feature added, please vote. The idea is this: a potential client visits your site and wants to know your availability. She sees that a particular day is available, and clicks on that day. She is then presented with a form that contains fields of information that the photographer deems necessary. After filling out the information, the data is emailed to the photographer, and that date is temporarily booked, pending payment. If you would like a calendar/booking feature similar to this implemented, please vote now

I would like to see the ability to set up dynamic galleries. For example, you could set up a gallery that contains all of your public photos with the keyword "sunset." Or all photos with a focal length of 200mm. Or all photos with a focal length >200mm AND the keyword "sunset." The ability to specify which galleries to pull photos from would be nice as well.

I would like to have the music you experience constant throughout a visitors visit to my site. It would very much help the cohesiveness of the site. It doing so it would be nice to set a group of tracks to play so one piece of music is not replaying in the event someone is on a site for any length of time.

I would like to be able to be more specific with coupons.. such as choose specific products or print sizes that the coupon applies too.

With the great new blog feature I was excited to start moving my current blog over. However I noticed that you need to add each photo individually rather than as a batch, this is going to be a slow process. I'm sure most photographers will want to put multiple photos in each blog post so to make the blog useful I think this is an essential modification.

Ability/option to present galleries exclusively in Slideshow mode (like the Home Page). This would make for a more professional looking website.
