I receive many msj of recycling, transportation, etc.
and I would really like to know if they spy on me or if they attack me.
How can I know? as simple as when I receive msj that the msj number appears in green and
as soon as I receive an espionage or an attack msj, the msj number changes color to red.

I'll explain it again but in a different way:

During the day I receive 1000 msj, transport, recyclable materials, etc. The msj number is deleted if you read or delete them.
my idea is that this number is green and if I have a spy msj or an attack msj, that number turns red.
If it's in the red, I look who spied me or who attacked me. In a speed universe it is elementary because nothing but spys you attack ..

Use the filter. It was created for exactly this purpose.

The filter filters the msj but it does not alert me that I am spied on or attacked.
I receive 2000 msjs and every time I get 1 msj I have to look if they spy on me or if they attack me.
for what? worth the filter? if for every msj I receive I have to look if I am attacked or spied on?
