?Program did very well, but if I no longer want to use AutoCAD, choose a different program that give me more. Why not insert new things, such as invoking the command line only with the letter "L" and not "L+ENTER", or simply draw a line on a clicking existing line? New things that would help further the work of designers, but with a interface similar to AutoCAD.

EDIT:

?I did not want to offend the great work done so far, I would like to clarify. The program works really well, and is lean and fast ... very important things! I just wanted to recommend to further improve the user experience of CAD through the integration of added value than the competition. Sorry again if I said something wrong or offensive ... and thanks for the wonderful work!
