What type of suggestion?: Feauture / Equipment buff
What does it do?: Minimap, When a T / Detective buys a radar, it provides a minimap on screen, that updates with shots in CLOSE proximity, shows player locations (not real-time, but updated within the same time as the radar) and should be able to 'mark' a few players at a time for real time updating, which also adds a FOVcone ( Field Of Vision cone, use
http://goo.gl/xGvzc as resource, the higlighted cones are the.. whatever they are's FOV) to those players and should last only a few seconds, Could be used to 'mark' spots on the map for other traitors/detectives to see, so that they can highlight where is not a good place to go, or where they should meet if the defacation hits the oscillation.
Why should it be added?: If this is applied as a whole, I think it could help promote a more tactical game, or introduce teamwork (A word oh-so-few TTT players know) and I could definitely see it making it more fun, and it's not really unbalanced in any regards as it is just a more visual approach to the radar, and if for some reason you do think that is overpowered, then taking your eyes off of your surroundings to either open it up for marking or to look at the bottom corner of your screen to check who's around you balances it out fairly, as it is designed to distract your eyes - even for just a second - to check your surroundings, and in doing so it could ultimately cause your death.
