I have been using WordPress for 3 years now.
I developped my own plugins.
Each time or so, i made an upgrade of WordPress, i had to review my plugin code about Admin menues.
The most sofisticated plugin i made is managing events like comments. Under the Comments menu item i have two new options : Events, Moderate Events. Of course, on both options, i can edit a particular event.
My plugin was working just fine till 2.2 (with little fixes).
But now i do not find the solution.
I found a bit frustrating that what you see under the admin panels cannot be 'easily' coded for your own needs.
You guys developping the Admin should consider reviewing the different items of the Admin as if they were ALL add-ons of the Admin. Each major options (Write, Manage, Comments, ...) would be coded with the same architecture.
This would ease the developpement and maintenance for you and 'sofisticated plugins' developpers.
Anyway thank you for the great work
