Is there a way I can keep the keyboard focus on the command line at all times?
For example I want to draw a triangle. I draw first line, then second line and I want to enter C to close it, but now the command line is not in focus any more and I have to click on it in order to write.
Also, is there a way to treat space as enter like in AutoCAD?
Although not a perfect way, there's a workaround :
After selecting the tool line 2 points, draw somewhere on your drawing 3 consecutive lines and enter c, it will close the shape and after that you can continue but the c command works after 2 drawn lines.
It's interesting if you have several triangles to draw, because you need to delete the original 4 lines figure you drew at the beginning
