There are several pages in your software that are dead end pages, meaning there is no way to easily get back a step from where you landed. Merchant services is a huge problem because when I need to do several transaction fixes or lookups, I have to continually go back to the More menu and drill down to Merchant Services after every transaction I look up, I can't just easily select a back to main page (to get back to the Merchant Servies main page) button or link. That absolutely needs to be available.
The same is true of the Teachers & Staff page, it's a dead end that gives you no way to easily go back to the main Teachers & Staff page without drilling down through the More menu. It's entirely user-UNFRIENDLY and non-intuitive. Back user experience every time I use these features in the software.
