I REALLY like the new tray icons.
I like having lots of choices for the icons that can be used.
A whole bunch of ideas to enhance the icons 
I really like that clicking on an icon brings up AppControl to the right place so I can investigate a value quickly. Nicely done!
I am on a 34" screen running at 4K and I find the text is very small. It would be really nice if I could maximize the size of the icons being displayed
Perhaps additional icons that includes a minimal label, a colon, and the metric
- C:
- M:
- CT:
- G:
- GT:
- NI:
- NO:
- P:
- D:
I noticed the terms “Network In” and “Network Out”. Would it make more sense to use the more common terms “Network Download” and “Network Upload” (and for the above labels “ND” and “NU”)
Would it be possible to add options to have tray icons for “Disk Writes” separate from “Disk Reads”? I am not sure I would use these at all, but if it can be done, some people might like that.
Another option to choose the colour for each icon could be helpful. If I could customize the colour, I might choose red for CPU and Blue for memory. In such cases, having an option of just the number might be good to (again) allow me to maximize the readability on my 4K resolution.
Another option to maybe make the icon flash if a metric passes a threshold? I guess - for me - the ideal would be to have:
- just 2 icons: CPU and Memory
- CPU would display just the metric in red (as big as you can make it)
- Memory would display just the metric in blue (as big as you can make it)
- CPU icon would flash if the CPU goes above a chosen value for more than a chosen number of seconds (I would probably choose over 80% and over 5 seconds)
- Memory would flash if utilization goes above a chosen value. I would probably choose 80%. I wouldn’t worry about length of time as I very rarely see memory utilization spike and return to a lower value quickly
An alternative to flashing icons (if flashing icons are not possible) would be to change the colour of the icon after a threshold is passed. In such a case, I would probably go with black icons that turn red when a threshold is passed.
