Something like this?
It sounds like a good idea.
You`re a coder, and I`m sure you type very fast, around 2-5 times faster than me.
So, for users like you it might be convenient. And also you know almost all the actions by heart.
I prefer to click. A separate tab will help me to organize. And considering that my knowledge is not that advanced, for me the browsing is a bit slower.
Maybe having the option to have clone windows for any Playmaker Editor Windows will be a way to achieve this.
Having the option to rename the window, to change the displayed content will bring us closer to this.
Maybe will serve as a temporary sollution to view multiple objects FSMs simultaneously?
