[Feature requests] TaskBar: MEM GB; no traffic used; even shorter traffic speed

[yalov]

1. In the taskbar, there is no setting to show memory in GB and not as %

2. The traffic per day information is not useful for me, so I would like option to not show in the taskbar tooltip, or, better, option to disable the feature of accomulating traffic size per day

3. "Short" trafic speed could be even shorter: 50K instead of 50K/s
