A feature that would be very helpful to me would be the ability to hold down some modifier key (such as CTRL) and then when I click on a shortcut in the Start Menu have it open the app but NOT close the Start Menu so I can then click other shortcuts.

I find myself positioning my finger on the Start key on my keyboard and quickly pressing it and then a app shortcut, and repeating in quick succession.

Being able to just hold CTRL and open multiple shortcuts without the Start Menu closing would be much easier.
