I notice that you stated that currently you cannot integrate notifications with mail app due to some limitation in the iPhone SDK, however a few "push" apps on the appstore are currently offering this feature....
Example: GPhushed

I'm hoping you can achieve the same with Notifications :)

We should be able to edit plugins from the application instead of having to go to the website

Perhaps you can integrate a google reader import and sync read/unread status etc to the superfeedr???

Could you add the option to open a selected RSS App to view a rss notification instead of opening the web page. In this way you could have the same feeds and have the option to view them when you want and mange the feeds better. Thanks

It would be really good if you can repeat a notification until cleared. This would be useful for late night support calls from our automated alert systems.

Also, could it be possible to create longer alert tones to go along with this?

There are times when a single alert chirp is not enough to drag me out of bed at 4am.

More sounds could be helpful for people who are using web api, because then they can assign particular sound to particular event. More variety would be suitable for those who are a few types of events.

I'd love to send and receive notifications rather than SMSs between friends.

Is it possible in the API to just leave the field "notification[run_command]" or "notification[action_loc_key]" open, so that when you get a push message, you can only click "OK"? Now, you can't, and you have to assign a function.

I know you don't support jailbroken devices, but this could actually be a much more generic feature. For example, the user could specify any URL or command based on a filter.

It'd be great if I could set the notification sounds and other "advanced" settings in one place for ALL my notifications. :)

i would love to be able to view the notifications even when my phone is offline, just to catch up with any missing notifications i have so far. this would be helpful in places where there is no network reception.

Twitbird Pro is far from new but has never been an option in here.

Right now i set my mail server to send a notification email to 4push upon mail arrival. But the front of the email is too long. The push message has become useless because I can't really see who the sender and what the msg is about

As I <a href="http://twitter.com/gnfti/status/4041186424">suggested</a> on Twitter earlier.

E.g. Use email notifications to open chess app. This way you will create a really generic notifications platform fed by email

Yes I can change email notification sounds. But emails from Facebook and Twitter seem to be exempt from this setting and they always use the default sound. Is this a bug or a design limitation?
