I am a fan of and comfortable with the current interface, likely because I'm a long time user of the product. But, I also understand that newer, less experienced users might be a bit overwhelmed and confused by the plethora of choices. Accordingly, consider this approach which, I think, provides a new level of usability without dumbing down the product.
2 user-selectable product interfaces:
1. The current TOOL-ORIENTED interface.
2. A TASK-ORIENTED interface, where, instead of seeing each individual tool, the user is presented with a menu of tasks that start the appropriate tool depending upon the action selected. So instead of seeing the Registry Cleaner tool, perhaps the user would select "Click here to scan and clean your registry" and Registry Cleaner would start, or "Click here to uninstall a program" and Software Manager would start, etc. Given the large number of things the program does, the interface could get a bit 'crowded' if not implemented properly, so maybe you only put those things on the menu that 85% of your users do 75% of the time. Or maybe you allow the user to create a customized menu, selecting only those tools that he/she would like to 'menu-ize'.
I love PT because it is not bloated - it does what it does quickly and efficiently without a lot of bells and whistles. I suspect that none of us want the program to become bloated and slow, so that would have to be a consideration. But this struck me as a possible compromise to all of the usability concerns I've been reading about on the forum lately.
Food for thought. Thanks.
