Status of gnss in the notification bar.

[jancelin]

Hello,

Thank you for making this great tool!

Is it possible to see in the notification bar, rather than a square, the type of positioning?:

• Normal> N
• DGPS> D
• FLOAT> F
• RTK> R

You may also use a colour code in conjunction with the letter, like in JOSM or RTKPlot:
Normal : Red
DGPS : Blue
Float : Yellow
RTK : Green

(JOSM screen shot; Normal : 5,0; DGPS: 4,0; Float: 2,0; RTK: 1,0)

And Connexion problem (Ntrip or GNSS receiver) -> X

It seems we should say "status bar", not "notification bar" :
