PIECEWISE editing improvement suggestion

[compsystems]

sorry for my bad English

TIM >> I'll investigate ways to make this more obvious
can be to place in the title bar a temp message, or create a temporary status bar
"use [,] to include a new condition"

Request: Please improve it in the next kernel upgrade, the following

No pretty print for (x < -pi) is displayed as (-pi > x) UGLY
same for x<0

Example
F1(x):=PIECEWISE( X<0, PIECEWISE( X< -pi , 4*sin(X), 2*X+5 ), 5-X^2 ) [ENTER] =>

F1(x):=PIECEWISE( 0>x, PIECEWISE( -pi > x , 4*sin(x), 2*x+5 ), 5-x^2 )
