This was an open suggestion, nothing in it was set in stone, meant to catch the eye of the developers, for them to decide what works and what not.
I personally would like to have it in corp/fleet chat windows or even the corp/fleet panel which makes it very private, having it manually activated makes it an option for you to use. But i will not go on on what would work and what not, it wouldnt change anything, they will do what they think is right for them.
Again, they can make simple and symbolic or intrusive and abusable, thats up to them.
I apologize as i wont reply any further, it was meant as a suggestion to them and if i could have done it privately i would have, so not to fuel up any unnecessary debates.
