A "cool" feature would be the ability to control the fan speed of your mac for times when your laptop gets really hot from watching videos or running certain applications.
The new MacBooks have passive cooling, so it would be interesting to know if it's been working on the edge.
Allow Toolbox to Monitor System Stats, CPU Temp, Fan Speed in Mac Notification Center Many Mac users like to keep a watchful eye on their system stats, including processor utilization, memory usage, disk activity, network usage, CPU temperature, fan speed, and perhaps battery stats. source for more on this: http://osxdaily.com/2016/03/13/monitor-system-stats-cpu-temp-fan-speed-in-mac-notification-center/ Thanks for your consideration!
That's not possible without digging really deep into the system and most likely will become obsolete soon due to Apple's decision to block kernel extensions in macOS
Have a temperature monitor with a display of it in the top bar and a nice app view to see the temperature of the MacBook to ensure it is running as expected
With all the tools already included in Parallels Tool Box I couldnt resist suggesting a fan control and display of all the parameters of your machine such as fan speed, CPU/GPU/RAM/ETC. temps to make sure everything stays within reasonable temperature while you are working especially running virtual machines.
such functionality requires very deep integration into macOS' kernel. Apple eradicates kernel extensions from macOS, so unfortunately we cannot provide such feature, although we would love to.
Fantastic new feature. Can it be expanded with following options? Allow choice of which sensor appears in menu bar (Efficiency Cores, GPU, etc). Additionally, perhaps allowing MAX option to show highest among the sensors. Adjust update interval, up to 60 seconds (seems to default to 5 seconds)
