[FEAT] Persistent labels

[larvanitis]

Is your feature request related to a problem? Please describe.

When multiple graphs are displayed, it is not clear what each one is.

Describe the solution you'd like

I'd like to have the ability to set some kind of labeling/legend, which will be visible at all times.

So for example, I'd like the net monitor to be like:

↓  42,0 KiB/s
↑ 483,5 KiB/s

and the disk monitor like:

R  84,0 KiB/s
W   1,0 MiB/s

This could be set in the configuration in the same way the colors are (eg "Custom Label", could be empty by default):

Also, it would be awesome if emojis were supported.

btw I believe "Text displayment" should be "Text display"

Hello, Do you think is enough to have only 1 checkbox on network graph and disks graphs like Show icons (↓ / ↑) ? Or you think we need an free text input ?

BTW, the alignement should only go on left or right to text and not aligned like you have mentioned, so the render should be something like :

 ↓ 42,0 KiB/s
↑ 483,5 KiB/s
# OR
 42,0 KiB/s ↓
483,5 KiB/s ↑
