Although it is admirable that the developers of a LibreCAD software, made an efforts for community. 
It can be understand at some extent that developers are not 'Pro' CAD users.
However, the efforts will go into the vain, 
if its not developed according to standard need (at least). Commercial standards is not concern here at all but Ideal for 
Printing and 
Academic project purpose where more time consumption is not a concern.   
For example, many 
open source software is very brilliant with their alternatives such as 
Blender with 
3DS Max / Maya, 
Inkscape with
 Adobe Illustrator, and 
GIMP with
 PhotoshopIn conclusion, see the image below in which the very 
simple drawing takes minutes to complete in LibreCAD, whereas the same drawing can be complete with seconds in AutoCAD or CorelCAD.
The proverb is best fit to LibreCAD is SLOW AND STEADY WINS THE RACE
