I like this feature.
However, it is too cumbersome.
Want To Add a Button，
Will be more convenient。
I have an idea。
Each window，Leave a space。
Depending on your window，Add a Custom Button。
So, don't have to design the window。
again, you can create a custom panel (using jsfl) to do that.
p.s. please do not post duplicate threads, 能否在时间轴上加些按钮呢？ add some buttons on the timeline？
