I can't until a tray icon for Speccy is developed.
Some features I would like to see in regard to this, especially when the mouse pointer is over the icon:
Quick temperature information
Battery information for laptops
Current number of processes running
Number of bytes,Kb,Mb, etc. being used/transferred
Voltage
Some additional features I think would be useful:
Notification when new hardware, flash drives, and periphials are connnected
When icon is right-clicked, a choice of the various sections should be displayed, along with tray/program options
A little pair of glasses as the icon (of course)
Any other suggestions are welcome.
