Ho OP, nice app. Just a few advice/request/feature change:
1. Please do try to add CPU usage. Many requests from people on the playstore reviews too.
I dont want to promise this. Adding CPU usage is not an easy task, and have some drawbacks:
- it needs much higher refresh rates (1sec, 0,5sec) to show "realtime" CPU information (lower refresh rate does not make sense)
- too much refresh will drain your battery
2. On switching the icon display off, the bars go off too. Instead there is only a text notification display for RAM. Few people on playstore complained of the same 2.
The normal (text only) notification can be expanded with 2 finger swipe down gesture.
Thats the way how notifications works in android. I can't change this behavior.
High priority notifications can be always(nearly) on the top of the notification drawer, and can be always(nearly) in expanded state (with the bars). BUT high priority notification can't be shown without an icon, the android API does not allow that.
If you turn off the notification icon, the notification will show with a low priority flag, but this way the notification will not be always expanded. And maybe other notifications will push down in the stack.
So, you have to choose: high priority, always on top, always expanded notification with icon, OR low priority notification without icon (which maybe collapses or get lower in the notification stack).
3. Can you please code for the service to stop/sleep on screen off and restart on screen on? This prevents wakelocks and conserves battery.
It's already working exactly in this way. Screen off -> service stops. Screen on -> service starts.
