topix,thanks for your response, you have added very interesting option, but I meant a slightly diferent thing:
You see, if I remove the image from the button "X" - it will look like this....

This gray button with borders... If all this could be transparent, but not the image (that I use in this button), then I could control transparency of the button - changing transparency of the image (in the graphic editor)...
Also, as You did: is it possible - to make individual management of transparency of each button (to make all remote translucent and some buttons opaque)?
And one more wish: could You add a option - to make transposition to "Start new line" (it could be usefull, in certain cases).?
