In Opus, If you initiate the circle command, click a point, the "Available Commands" window pops up in the top left corner of the Opus window. If you select your diameter or radius, the "X-Offset and Y Offset" window pops up. It would be nice if we could get those windows to trail the cursor. When someone is typically drawing in Opus, it is much easier for someone to look in one spot for all of the available information (the cursor location). As of right now, it does tell you relevant information by your cursor when drawing in Opus, but this could be much improved.
Possible Bug?: Start typing in "Line" to initiate the line command, type in "LI", then move your mouse in any direction. The movement of the mouse exits you out of the existing command. Can we have it work like Autocad please?
