While it might make sense to some for the Formidable menus to be right below comments in the administration interface, it is inconsistent with all the other plugins whose top-level menus are located in a section below everything else from core, right after the Settings top-level menu.
For example, GD Star Rating, Download Monitor, NextGEN Gallery, Calendar, WP-Polls, WordPress CEO all create a top-level menu below the core top-level menus.
Formidable is the lone sheep who seemingly tries to get more prominent placement at the cost of UI consistency. It actually makes it harder to find Formidable since users are used to finding new plugin content management features near the bottom of the left sidebar.
Please, for consistency's sake, consider relocating the menu for Formidable.
