Far from it, your program is really one of the easiest ones available right now. It is doing exactly what most admin want it to do without all sorts of additional things that most people wont miss. My group at Mappers United use rconNet program for the senior admins simply because of some of the higher level features. I like it but for ease of admining a server I found that your YARCC is much more comfortable for my other admins to use. I used it the other night as well and was very happy using it compared to the other program.
You have a winner going with this so stick to it.
We run a couple of BF3 servers now so a nice feature would be to have the option to save both to allow us to jump quickly from one server to the other.
