TTop: System monitoring tool with TUI, historical data service and notifications

Was linux user/sysadm for years and used a lot of different tools like top, htop, sar and atop, but it was never a tool which is simple and with all values I wanted in my terminal for fast trouble-shooting: no df (atop), or no historical snapshots (top, htop) and etc

So, I decided to take it in my hands and spent few days to create my own ttop
